Stem cells are cells found in most multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s.
Stem cells can develop into any cell type. They are valuable as research tools and might, in the future, be used to treat a wide range of diseases. Credit: Judith Stoffer
The two broad types of mammalian stem cells are: embryonic stem cells that are isolated from the inner cell mass of blastocysts, and adult stem cells that are found in adult tissues. In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.
Stem cells can now be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Highly plastic adult stem cells from a variety of sources, including umbilical cord blood and bone marrow are routinely used in medical therapies. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning have also been proposed as promising candidates for future therapies.

Articles about stem cell/islet cell transplantation(allo) are more in lay press than in scientific journals.They are still in experimental phase,on animals and lot more genes to be discovered before be in vogue.

| Stem cells are unique because they combine two key properties: Pluripotency and self-renewal. Pluripotency means that they can differentiate and give rise to multiple different cell types.social bookmarking list |
