The accomplishment of tissue engineering for cartilage for ailments like osteoarthritis will be dependent on the interactions amongst the cells, the matrix, and mechanical forces directed against the joint.

The extracellular matrix- the framework and the content inside the framework the stem cells cling to- plays a vital function in tissue perform, dictating its physical and mechanical properties, maintaining the spatial arrangement of the cells that reside within it and controlling the complicated crosstalk that exists in between the cells, the matrix and exterior forces. The matrix controls cell dimensions, form, motion and alignment through its about three-dimensional architecture and adhesion… the stickiness of the stem cells.

While the matrix exerts its results, the cells have an effect on the matrix by applying traction forces and by synthesizing and degrading matrix. In addition, the interaction among the matrix and stem cells is responsible for triggering a assortment of particular mobile capabilities. It has grow to be increasingly obvious that the mechanical environment is equally essential as, and synergistic with, the chemical surroundings in directing cell conduct.

Signaling pathways spurred on in reaction to mechanical (load-bearing) forces are important for the maintenance and perform of tissue mobile function. Load-bearing smooth tissues this kind of as tendons and cartilage which consist of a network of fibrous protein (predominantly collagen and elastin), embedded in a gel of proteoglycans, glycosaminoglycans and glycoproteins exhibit specific attributes of tissue biomechanics and subsequent mobile responses.

Investigations in these unique tissues and designed are speedily expanding our knowing of a new region of medication known as mechanobiology.

Profitable tissue engineering demands a comprehensive comprehending of mechanobiology and in certain the loading circumstances experienced by the cells beneath physiological situations, in purchase to build how this controls mobile capabilities.

Clarification of mechanical pathways must offer helpful info for tissue engineering and regenerative purposes as well as even more insight into mechanisms involved in ailment processes.

The population of the Western world is getting older. As a immediate consequence, there will be an increase in diseases that can be linked with aging, these as joint issues.. These maladies not only have a negative influence for the patient, but will also have a important affect on the wellbeing care technique. Therefore, it is really important that much more active, less traumatic and less pricey techniques and tactics are developed for the therapy of these illnesses. The expectation is that nanotechnology will give an essential contribution to the advancement of this kind of techniques. Implants and tissue substitutes are created from biomaterials that have one particular frequent residence, i.e. biocompatibility. A promising software of nanotechnology is the development of greater performing biomaterials.

A current approach to the design and style of subsequent-generation tissue regeneration supporting biomaterials is concentrating on the framework at the “nano” scale. The underlying concept is that nanometer structure matches with the normal extracellular matrix resulting in an enhanced interaction of the tissue-forming cells in contrast with typical biomaterials. Recent developments in the industry of nanotechnology offer effective resources to modify the surface of biomaterials by introducing synthetic mapping and particular surface chemistry on the material. It is properly-recognized that each topography and surface area chemical composition influence the reactions of the biological surroundings to the system.

Human mesenchymal stem cells occupy a certain stem cell specialized niche, and consist of these stem cells that can differentiate into cells of mesenchymal tissues, including osteoblasts, adipocytes and chondrocytes.

Osteoarthritis is the most widespread musculoskeletal condition and triggers a significant social and psychological drain on those influenced as effectively as people who treatment for them in addition it sales opportunities to substantial financial expenses. This condition is characterized by articular cartilage degeneration and harm to the underlying subchondral bone. To date, there is a absence of successful therapies to handle the illness, resulting in total joint arthroplasty (joint substitute surgery) as the only viable therapeutic choice. Thus, there is a require to create techniques that are significantly less invasive and capable of regeneration of articular cartilage.

The use of autologous chondrocytes in tissue engineering purposes promises an avenue in conditions of efficacy and basic safety resulting in mesenchymal stem cells (MSCs) getting deemed an ideal therapeutic candidate for cartilage fix. MSCs acting by way of numerous development mechanisms are also known to avoid OA progression right after injection into the joint.

At our middle, we are continuously incorporating more recent ways to the introduction of stem cell technology for the remedy of osteoarthritis.

Our approach now is distinct from the way it was a calendar year back… and it will be diverse a year from now as we discover far more about nanobiology.

Future Remedies for Breast Cancer

September 2, 2011 By Leave a Comment

Regular therapy for breast cancer has substantially improved survival for ladies, but the fact remains that 40% of girls nonetheless eventually die from the disease. This truth highlights theneed for new and better therapies. Standard anticancer therapies mainly consist of medication and ionizing radiation that damage DNA and DNA machinery. This kind of solutions preferentially kill certain kinds of cancer cells considering that these cells have a diminished capability to survive the harm. However, standard cells, can endure DNA damage, but have the ability to repair their DNA. Regrettably, the identical genetic defects may well possibly render some cancer cells resistant to treatment, simply because they may possibly also be much significantly less adept at activating cell death in the face of DNA harm. The challenge of cancer remedy now is to take gain of qualities of cancer cells that distinguish them from common cells and to subsequently and especially focus on cancer cells. A growing knowledge of cancer cell biology is major to a lot better techniques for dealing with the sickness by directly exterminating only cancer cells. Listed are some of the most recent new and adventurous tactics that are being produced for foreseeable future breast cancer diagnosis and treatment.

Six new breast cancer remedy strategies

one. Oncolytic viral remedy – takes reward of molecules that tumor cells absence. Tumor cells typically lack the protein p53 which controls the cell cycle and cell replication. Viruses can attach to a host cell and replicate constantly inside the cell. They then burst out when their quantities are adequate, killing the cell and infecting its neighbors. An adenovirus has now been built that lacks the gene for the p53 protein this virus can consequently only replicate in cells in which p53 is already inactivated-such as several sorts of cancer cells. If this modified adenovirus is injected into a tumor, it will replicate in and kill only the cancer cells that lack p53, leaving standard cells unharmed. This method is presently undergoing clinical trials.

]]>

two. Interventional Radiology – Researchers are investigating a strategy in which magnets are employed to pull chemotherapy medication into tumors. Microscopic magnetic particles are connected to the cancer drugs and infused into the blood vessel that feeds the tumor. A uncommon earth magnet is positioned right over the tumor net website. The magnet pulls the drug-carrying particles out of the blood vessel right into the tumor. This technique is nonetheless experimental even so, early research is promising. Researchers desire that it will bolster the effects of chemotherapy and stop drug facet effects.

a few. Gene Remedy – includes the alteration of the patient’s genetic materials to fight or avoid cancer. Despite the simple fact that the science of gene treatment is nonetheless in the experimental phases, scientists desire that in the future the remedy can be employed as follows:
Alter the cells of a patient’s natural immune plan with cancer-battling genes that permit cells to a good deal far more forcefully assault the cancer
Genetically alter cancer cells so that the patient’s own immune strategy will defend against them and permit the altered cancer cells to act as a cancer vaccine
Substitute genes accountable for cancer growth with “excellent” genes and inject a tumor with genes that will make it much a lot more prone to cancer-battling agents.
Make normal tissue resistant to chemotherapy, so that medicines will ruin tumors with no detrimental healthful tissue.

four. Breast Cancer vaccines – Vaccination techniques are turning out to be created that engage the patient’s personal immune plan to eradicate cancer cells. The reward of this is very low toxicity, and higher specificity as nicely as a sustained antibody effect due to cell memory.

five. Use of breast cancer resistance genes – Researchers at the Dana Faber Cancer Institute have found out a gene that can predict a substantial danger of cancer recurrence in some breast cancers that have been handled with chemotherapy medications. This finding could guide the physician in the choice of anti-tumor medications to use and remove incorrect ineffective choices.

six. A great deal more specific breast cancer diagnosis – Breast cancer can now be characterized at a molecular level by obtaining expression profiles for countless numbers of genes within the cancer. These profiles can be grouped into subclasses of breast cancers that share widespread features this sort of as prognosis and probable reaction to certain solutions. A lot more precise treatments can then be made for every subclass of cancer.

Stem cells had been a wonder found some time again and have ongoing to confound doctors and specialists ever before given that. Originally they were extracted from the bone marrow which was a painful and risky procedure. Very number of donors could be found for this transplant and thus individuals ongoing to endure with their ailments and generally died because of it.

India has been researching on stem cells for a lengthy time and the latest development lifts the spirits and makes the potential of regenerative health-related science appear vivid and promising. Hematopoeitic cells have been found in umbilical cord blood, the stem cells identified here are far more in range and greater in quality compared to the bone marrow stem . They can be extracted and collected with out ache and be set to use to heal a quantity of ailments like cancer, arthritis, anaemia etc. Stem cells therapy is furnished in a number of stem cell hospitals in India today.

Stemcyteindia is a joint enterprise of Stemcyte Inc. USA, Apollo hospitals and Cadilla pharmaceuticals, it has some of the greatest folks in the planet major it is investigation and health-related group. Stem cells from the umbilical cord divide and can also kind into red blood cells, T- cells and platelets that make up the immune program. They are unspecialised and are also identified to renew and create into heart, nerve and muscle cells.

Not only are these therapies and transplants employed to heal illnesses they are also utilized publish medical procedures to exchange damaged cells like in chemotherapy or soon after a breast surgical procedure! Umbilical cord blood is a prosperous supply of these cells and can be stored by the family members for use in long run healthcare needs. It is ethical and permissible in India and the cells keep on to multiply for generations therefore supplying long expression solutions.

This miracle can effectively be comprehended by people who have earlier misplaced their cherished ones to terminal sicknesses like cancer. Absence of remedy and donors declare a range of lives, but not anymore, cord blood is quickly accessible and has a larger achievement rate in remedy.&#thirteen

Various Stem Cells For Future Treatments

May 30, 2011 By 3 Comments

Report by wayne chans







The isolation of human embryonic stem cell lines in latest years has actually produced a vast pleasure between scientists and other folks about the possibility of creating quantities of transplantable beta cells.

Given that then, much more and far more individuals have started out thinking about employing stem cells financial institution or a cord blood financial institution to shop their children’s stem cells in circumstance they turn out to be unwell and get conditions like leukaemia, diabetes or a cancer. As the collection of umbilical cord blood cells can only be performed just right after the infant is born, the determination can only be produced by the mothers and fathers before providing birth.
The stem cells collected are usually stored at extremely reduced temperature by employing cryopreservation.
This procedure is utilised to freeze the stem cells to preserve them and only use them when necessary, regardless of whether it is ten many years or twenty years later on.

Even although everyone is very thrilled about the choices and guarantees of treatments, there are even now gaps in our expertise of the cells that can be extracted to produce transplantable beta cells.
It is critical to know that there are in fact many various possible sources of cells for beta cell replacement, each obtaining its advantages and negatives.
Embryonic stem cells are on of them, along facet grownup stem cells and pancreatic beta cell lines.
Mostly due to the fact of the ethical unease about embryonic stem cells, many of the scientific studies completed have been directed toward which includes beta cell differentiation from grownup stem cells from the pancreas or the bone marrow most of the time.
Even even though several men and women have claimed that stem cells from ectopic organs like the bone marrow can be induced to differentiate into a variety of cell kinds these kinds of as neurons for illustration, there have been no scientific studies in which beta cells have been generated from adult stem cells outside the pancreas. It is virtually specific that such studies will be undergone at some stage though.
It as truly been known for some time currently that the pool of beta cells can be regenerated when positioned under tension by a range of manipulations, such as partial pancreatectomy. Pancreatic cells can differentiate in vitro into mature beta cells. Some scientific studies have identified that duct cells can give rise to endocrine cells. Others have proposed that beta cells can be created from other endocrine cells inside of the islet.

A discovering that has created some interest and also controversy entails a population of nest in-optimistic cells in the pancreas that has been proven to give rise to a range of cell kinds, which includes pancreatic endocrine cells and hepatocytes.

Bioinformatics, Bio-medicine and Gene Manipulation in Drug Development and Future Medical Care

June 25, 2009 By Leave a Comment

BIOINFORMATICS, BIO – MEDICINE, AND GENE MANIPULATIONS IN DRUG DEVELOPMENT AND FUTURE MEDICAL CARE.

Dr.T.V.Rao, MD

Bioinformatics is an emerging science which brings together the fields of Microbiology, Molecular Biology, Bio Technology and Genetics under the fold of computers and Software Advances in Computer Technology. Thanks to James Watson – Crick in basic understanding of the Bacterial DNA (genome). The coding of Chromosomes through the Super Computers; Databases and Software Technology perfecting the code of life, now Bioinformatics has become a big enterprise. Research reports, from all round the world (300 Laboratories) presented recently during a major genome conference at Cold spring harbor laboratory showed clearly that an exciting technology is born. We doctors in the past looking the problems of life and disease through clinical medicine, few laboratory tests and other technical advances. The Bioinformatics is changing the entire concept, in future we may be compelled to view life and disease through the Chemistry of Genes. The facts about the human genome project were made public on the Internet by US department of energy and National Institute of Health, making the approach easier to any scientist or Doctor to learn the genomic science to utmost detail.

1. Basic findings of Genome Project: a) Basis of life is equal between two individuals upto 99.9% extent, secret of difference lies in only 0.1%, contributing to our individuality. b) There are approximately 30,000 Genes. c) Genetic Mutations are common in males, so men are agents of change. d) so Genetic diseases are common in men.

2. Computer Speaks (Bio information): With feeding of complicated information to a computer, it speaks that life is a pack of information with a clear message that book of the life written in the complex DNA consisting of four letters. A.T.G.C.

A = Adenine; T =Thymine; G = Guanine; C = Cytosine.

At present we have > 85% of information on 23 pairs of Human Chromosomes. In future science expects that Physician can solve many mysteries of disease just looking into a computer and the greatest advantage lies in detection of most of the Genetic disorders. In future many diagnostic tests may be done by Bioinformed computers, the chip locating abnormal base pairs at different gene locations. Now in many Nations scientific organizations of repute are on a path to Bioinformatics with aim to make the recent science available to many.

3. Bioinformatics and Gene Therapy: Gene therapy suffered with many problems in the past will have a greater revival with better understanding of human genome. Many gene therapy trails will become virtual realities.

4. Bioinformatics and Proteomics: The knowledge of information about the Genes and Science of Genomics lead to science of proteomics To catalogue and analyse every protein in human system. The science of proteomics (Structural Genomics) will revolutionise the understanding of Hormones, Immunoglobulins targeting infections and Enzymes that build or break down energy reserves. We are aware now, that there are too, many proteins which guide our life (50,000 to about 2 millions). But few Proteins play the real orchestra, modifying different actions. Already many Bio Technology firms have started proteomics programme, if the events succeed to desired expectations there will be better quality of life serving to minute details.

5. Human Genome Project – Drugs of Future: At present we use certain drugs with a broad understanding to target only 500 proteins in the body, out of the 30,000 proteins already known to us. Because of the better understanding of Genome, Scientists have a good understanding on what happens if drug acting down to molecular level. Till now many drugs are experimented on trial and error basis mainly intervening at the level of signs and symptoms, and few at cellular levels.

With advances in Genomic Medicine there will be more rational approach in drug discovery and clinical application. In future it is possible to target the diseases like Diabetes and Cancer before the onset of physical disease (phenotypic expression). The scientific visions include interfering with the sick cell, sparing the healthy cells, making the therapy least toxic and harmful. The discovery in this direction lead to discovery of Monoclonal antibodies, choosing the particular receptor on the cancer cell responsible for propagation of disease. Already 12 such drugs are available in developed countries prominent being Herceptin, if blocks the HE-2/neu receptor, which is prominent on some breast cancer cells. Tepper’s group is on the way to find a Monoclonal which can block the common receptor for cancers like breast, prostate, lung and colon to create a super drug for many cancers. With better understanding on Bioinformatics Anti Cancer Drug discoveries will be target oriented with least toxic effects.

6. Genomic Based Drug Discovery: Alfred Gilman, a pharmacologist and winner of 1994 noble prize for his work on Cellular Signaling Mechanism, is now working with goal to trace the map of chemical pathways in the cells and use the knowledge to create virtual cell with all the pathways in a computer. Now the drug companies are using the Bioinformatics algorithms to predict the functions of proteins encoded by newly discovered genes. Many drugs discovers are moving to fast growing new area of Computer Science to fuel their endless quest for newer drugs and better targets.

7. Major Diseases on the List of Pharmaceutical Industry

The following diseases are being targeted by many drug firms with Bioinformatics include: AIDS, Mental Illnesses, Auto Immune Disease, Obesity, Alzheimer ’s disease, Heart Disease and Parkinson’s Disease.

From Experiments to Reality

The sequence of events from Discovery of Noble Laureate Joshua Lederberg (1958) on exchange of DNA within such chromosome pairs leads to process of homology recombination expressing in Genetic variation in the population. The present events of discovery by Mario Capecchi and Oliver Smithies applied the homology recombination in mammalian cell. The homologues recombination could take place between introduced DNA the cell Chromosome may even repair with the help of induced genes and awarded the Nobel Prize in 2007. The present study by them has targeted role of Genes involved in Mammalian organ development. Several human inborn errors an be targeted in events of malformation. If the future experiments are successful mouse models will be used for gene targeting The art of Medicine will be enriched with biology as source of future developments in Medicine.

Changing Role of Biology on Medicine: We are understanding more of Genes and inheretence.The quest to discover disease linked genes reaches all time high. Now it is understood the 3 million DNA bases in the Human genome have identified that about only one tenth, of one percent (Million) differ from one person to another. Variation in these particular letters called SNIPS or SNP’s, for single nucleotide polymorphisms have replaced genes as unit of heredity.

Role of Bioinformatics and Bio-Medicine on the Medical Profession: In the near future, every standard text book on Medicine, articles, journals published from reputed medical institutions emphasize the origin of disease on Genetic basis locating, few base pairs of Genes responsible for any complicated disease. The treatment approaches will be on targets of pathological process rather than vague remedies. We teachers in medicine should concentrate in understanding the role of Genes in disease and spread the message to our students. Let us learn to understand many diseases have a genetic basis and unlock the problem with a right key. Let there be more workshops, CME’s & Seminars on orientation of Bioinformatics and Biomedicine to our Doctors, so that we do not remain as Apes in front of a Bioinformed Computer.

Dr.T.V.Rao works as A professor in Medical Microbiology in India and interesting in propagation of futuristic ideas in science and Medicine to develop creative ideas in younger generation.

Stem Cell Treatments Offer Hope for the Future

April 6, 2009 By 17 Comments

Article by David Johnson





Stem cell treatments, research and technology is permanent fixture in 21st century medical research. Continued efforts to research and develop embryonic stem cell treatments and procedures doesn’t merely mean cloning human beings or involve moral and ethical controversies or issues surrounding such research. Embryonic stem cells provide the basic building blocks and structure of the development of various cellular and tissue structure in the human body, and stem cell research irrefutably offers potential treatments that may eventually cure many disease processes, enable people with spinal cord injuries to walk again, and guide researchers to develop medications that will end to cognitive impairment diseases such as Alzheimer’s and Parkinson’s Disease.

Millions of cells found in the human body can and are being developed for future medical treatments. Stem cells contain specific instructions on how cellular structures replicate and function. Each cell is also programmed with how long it will live, its specific functions and tasks.

Stem cells come from different sources. The most commonly studied, and used, stem cell therapies involve:

â• ¢ Embryonic stem cell therapy
â• ¢ Adult stem cell therapy and research
â• ¢ Umbilical cord stem cell therapy

EmCell Therapy
Professor Alexander Smikodub, M.D., PhD, is the founder of the Cell Therapy Clinic of the National Medical University and EmCell Clinic, as well as the inventor of treatment methods using embryonic stem cells in. The EmCell therapy Clinic has been offering embryonic stem cell treatments in vivo to improve physical health for nearly two decades and has helped thousands of people suffering from disease processes like Parkinson’s, multiple sclerosis, diabetes, various types of muscular dystrophy, blood diseases and cancers.

Dr. Smikodub has performed thousands of embryonic stem cell transplants to international patients who arrived every month from foreign destinations such as China, Germany, and the United States (where stem cell therapy treatments have not been approved) to receive treatments that improve quality of life.

International Clinical Experience
The EmCell therapy Clinic is one of the world’s largest fetal or embryonic stem cell transplantation centers that addresses various conditions and disease processes. Embryonic stem cell research and development continues to offer curative effects, which is one of the most promising aspects of cell research and therapies. The am so clinic focuses their attention on embryonic stem cell transplantation related transplantation of the basic building blocks of all tissues and organs, not the tissues or organs themselves, that are responsible for various functions in the body and provide the basic structures for musculature, blood, immune system, nervous and other body systems.

Stem cell therapies, and most potentially the potential of utilizing embryonic stem cells offer a multitude of benefits including but not limited to enabling cells to migrate directly to the site of injury or damage for repair or replication, establishing intercellular linkage and differentiation (developing into specific cellular structures such as muscle tissue, heart tissue, or neural tissues), In addition, benefits include enhancing immune responses and reducing and avoiding tissue and organ rejection.

EmCell, based in Kiev, Ukraine, was founded in 1994, a private clinic that has gained international recognition and reputation in the field of embryonic stem cell research and clinical applications. Focusing on effective prevention and antiaging programs, and devising and developing treatments and follow-up for complex clinical cases, the EmCell clinic focuses on indications as well as contraindications for severe acquired and genetic disease processes that are caused by decreased cell counts.

Embryonic stem cell research and development continues to be the most effective stem cell therapy yet developed by researchers and scientists. Embryonic stem cells are commonly cultivated from discarded fetuses or embryos resulting from abortions, and can be utilized to provide life-saving treatments for dozens of disease processes and health conditions.

Medical Stem Cell Tourism
The United States does not currently approve of stem cells therapy options, but Americans and other international travelers seek international destinations for promising treatments. Today, thousands of medical tourists venture to locations throughout the world, including China, Thailand, Japan, Europe, and India for treatments that offer beneficial and promising results.

The cost of therapies is determined according to geographic location of treatment facilities as well as the injury, illness or disease being treated. The U.S. is currently funding Phase I clinical trials of some types of stem cell therapies that may provide productive and beneficial use in the near future. In the meantime, individuals can reap the benefits of stem cell research and therapies offered around the world, such as the facilities found at EmCell Therapy in Kiev, Ukraine.

Our, EmCell, clinic offers advanced patented methods of stem cell treatment for different diseases and conditions. At present, EmCell Clinic successfully applies its own method of fetal, stem cell treatment.
