A stem cell possesses two properties: . Self-renewal is the ability to go through numerous cycles of cell division while still maintaining its undifferentiated state. Stem cells can replicate several times and can result in the formation of two stem cells, one stem cell more differentiated than the other, or two differentiated cells.
The morphology and growth factors of these lab induced pluripotent cells, are equivalent to embryonic stem cells, leading these cells to be known as induced pluripotent stem cells (iPS cells). [75] This observation was observed in mouse pluripotent stem cells, originally, but now can be performed in human adult fibroblasts using the same four ...
Pluripotent adult stem cells are rare and generally small in number, but they can be found in umbilical cord blood and other tissues. [48] Bone marrow is a rich source of adult stem cells, [49] which have been used in treating several conditions including liver cirrhosis, [50] chronic limb ischemia [51] and endstage heart failure. [52]
Thus, embryonic stem cells are likely to be easier to isolate and grow ex vivo than adult stem cells. [36] Embryonic stem cells divide more rapidly than adult stem cells, potentially making it easier to generate large numbers of cells for therapeutic means. In contrast, adult stem cell might not divide fast enough to offer immediate treatment. [36]
Induced pluripotent stem cells were first generated by Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University, Japan, in 2006. [1] They hypothesized that genes important to embryonic stem cell (ESC) function might be able to induce an embryonic state in adult cells.
There is other stem cell research that does not involve the destruction of a human embryo, and such research involves adult stem cells, amniotic stem cells, and induced pluripotent stem cells. In January 2009, the US Food and Drug Administration gave clearance to Geron Corporation for the first clinical trial of an embryonic stem-cell-based ...
