Our goal of use of stem cells in clinical practice is far from true. An intensive research is going to realize the promise of novel cell-based therapies. There are few needs that must be fulfilled before stem cells can be used in clinical practice. we must be able to manipulate stem cells so that they [...]
Clinical Applications of Stem Cells – What Could Be Possible?
June 19, 2009 By Leave a Comment
Stems cells are promise of the future. There are a number of conditions where stem cells have potential application and tere are many ways in which human stem cells can be used. One of the primary goals of stem cells is to identify how undifferentiated stem cells become the differentiated cells that form the tissues [...]
What Are Induced Pluripotent Stem Cells?
June 17, 2009 By Leave a Comment
Induced pluripotent stem cells (iPSCs) are adult cells that have been genetically reprogrammed to an embryonic stem cell–like state by being forced to express genes and factors important for maintaining the defining properties of embryonic stem cells. Although these cells meet the defining criteria for pluripotent stem cells, it is not known if iPSCs and [...]
Fibrin Microbead – Would It Improve Clinical Application of Stem Cells
June 17, 2009 By Leave a Comment
One of the major difficulty in stem cell linical application is the inability of cellular structures to integrate and survive and repair the damaged target tissues. Injected single cells also survive poorly and can hardly integrate in tissues. A practical solution is to deliver the cells on small particulate matrix, in a manner that can [...]
What Is A Stem Cell bank
June 13, 2009 By Leave a Comment
A cell bank in its simplest form is a collection of containers of cryopreserved cells that are intgral part of a homogenous cell suspension derived from a single culture of cells.Cells are stored at ultra-low temperature and in this state the cells remain viable indefinitely. On thawing they are able to divide again. A cryopreserved [...]
Link Between Stem Cells and Regenerative medicine
June 10, 2009 By Leave a Comment
Regenerative medicine was the term coined by William A. Haseltine in 2000. This tries to heal the body by stimulation of endogenous cells to repair damaged tissues, or transplantation of cells or engineered tissues to replace diseased or injured. Tissue injuries are normally repaired by formation of fibrous scar tissue in humans. But a number [...]
A Protein That Induces Stem Cells Found To Stimulate Muscle Regeneration
June 9, 2009 By Leave a Comment
A protein called Wnt7a has been found to increase the number of stem cells in muscle tissue, leading to accelerated growth and repair of skeletal muscle. This has been found in a study research at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa. The finding shows that, by targeting stem cells to [...]
International Policy on Human Embryonic Stem Cell Research
June 8, 2009 By Leave a Comment
The policies on human embryonic stem cell research used by different countries vary tremendously and change frequently. The policies are determined by the government stand religious stand and political awareness etc. Here is major categorization Permissive: This policy allows various embryonic stem cell derivation techniques including somatic cell nuclear transfer (SCNT), also called research [...]
Embryonic Stem Cells and Regenerative Medicine
June 5, 2009 By Leave a Comment
Under appropriate culture conditions, embryonic have demonstrated a remarkable ability to self-renew continuously, that is, to produce more cells like themselves that are multipotent. Human embryonic stem cells that have been propagated for more than two years also demonstrate a stable and normal complement of chromosomes. This is in contrast to the unstable and abnormal [...]
Hematopoietic Stem Cells – An Alternative?
June 4, 2009 By Leave a Comment
Role of bone marrow transplants in increasing the survival of patients with leukemia and other cancers, inherited blood disorders, and diseases of the immune system and it is an inspiration to stem cell research. Hematopoietic stem cells are used in bone marrow transplant and have the ability to self renew in the marrow and to [...]
