   Stem cell tourism is the part of the medical tourism industry in which patients travel to obtain stem cell procedures. [109] The United States has had an explosion of "stem cell clinics". [110] Stem cell procedures are highly profitable for clinics. The advertising sounds authoritative but the efficacy and safety of the procedures is unproven.

3. 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.

5. 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.

6. Induced pluripotent stem cell - Wikipedia

   en.wikipedia.org/wiki/Induced_pluripotent_stem_cell

   Induced pluripotent stem cells are similar to natural pluripotent stem cells, such as embryonic stem cells, in many aspects, such as the expression of certain stem cell genes and proteins, chromatin methylation patterns, doubling time, embryoid body formation, teratoma formation, viable chimera formation, and potency and differentiability, but ...

7. Embryonic stem cell - Wikipedia

   en.wikipedia.org/wiki/Embryonic_stem_cell

   Embryonic stem cells of the inner cell mass are pluripotent, meaning they are able to differentiate to generate primitive ectoderm, which ultimately differentiates during gastrulation into all derivatives of the three primary germ layers: ectoderm, endoderm, and mesoderm.
