2. Stem cell - Wikipedia

   en.wikipedia.org/wiki/Stem_cell

   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. Epigenetics in stem-cell differentiation - Wikipedia

   en.wikipedia.org/wiki/Epigenetics_in_stem-cell...

   Embryonic stem cells exhibit dramatic and complex alterations to both global and site-specific chromatin structures. Lee et al. performed an experiment to determine the importance of deacetylation and acetylation for stem cell differentiation by looking at global acetylation and methylation levels at certain site-specific modification in histone sites H3K9 and H3K4.

4. 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.

5. Stem cell transplantation for articular cartilage repair

   en.wikipedia.org/wiki/Stem_cell_transplantation...

   Stem cells, as a concept, originated as a theory in the 19th century to potentially allow certain tissues to self-renew. There are five types of stem cells, and MSC's are multi-potent, meaning they are cells that have the ability to develop into more than one type of specialized cell. Mesenchymal stem cells were originally discovered and ...

6. Endogenous regeneration - Wikipedia

   en.wikipedia.org/wiki/Endogenous_regeneration

   Endogenous regeneration in the brain is the ability of cells to engage in the repair and regeneration process. While the brain has a limited capacity for regeneration, endogenous neural stem cells, as well as numerous pro-regenerative molecules, can participate in replacing and repairing damaged or diseased neurons and glial cells.

7. Knee cartilage replacement therapy - Wikipedia

   en.wikipedia.org/wiki/Knee_cartilage_replacement...

   Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
