2. Adult stem cell - Wikipedia

   en.wikipedia.org/wiki/Adult_stem_cell

   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.

   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]

   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]

5. Stem-cell line - Wikipedia

   en.wikipedia.org/wiki/Stem-cell_line

   A stem cell line is a group of stem cells that is cultured in vitro and can be propagated indefinitely. Stem cell lines are derived from either animal or human tissues and come from one of three sources: embryonic stem cells, adult stem cells, or induced pluripotent stem cells. They are commonly used in research and regenerative medicine.

6. Embryonic stem cell - Wikipedia

   en.wikipedia.org/wiki/Embryonic_stem_cell

   Embryonic stem cells is one of the sources that are being considered for the use of tissue engineering. [19] The use of human embryonic stem cells have opened many new possibilities for tissue engineering, however, there are many hurdles that must be made before human embryonic stem cell can even be utilized.

7. Stem-cell therapy - Wikipedia

   en.wikipedia.org/wiki/Stem-cell_therapy

   Research using both hematopoietic adult stem cells and embryonic stem cells has provided insight into the possible mechanisms and methods of treatment for many of these ailments. [56] Fully mature human red blood cells may be generated ex vivo by hematopoietic stem cells (HSCs), which are precursors of red blood cells.
