A recent study published in June 2010 that looked at 2000 (approximately) clinical studies in biomedical research highlighted the capabilities of cell therapies. While embryonic cell manipulation is limited and controversial, the development of engineered tissues from iPSC for medical interventions in serious conditions has a better chance.

Adult stem cells have been discovered in post-fetal animals.
Linage-committed stem cells include hematopoietic stem cells, which can become red or white blood cells, and mesenchymal stem cells, which can become a variety of tissues such as bone, tendon, ligament, cartilage, heart, liver, or nerves. Adult stem cells can be found in a variety of places, including bone marrow, fat, brain tissue, and muscles. Fat is the tissue that produces the most mesenchymal stem cells, whereas bone marrow and umbilical blood produce more stem cells that will eventually become red or white blood cells. There are several types of stem cells available, including autologous, allogenic, and xenogeneic stem cells. Autologous stem cells are those derived from the patient’s own animal. Because there is no risk of rejection, these are the best for transplantation. Allogenic stem cells are derived from the donor’s own species. Stem cells can potentially be used without fear of the host tissue rejecting them because they lack the standard cell surface markers that trigger immune responses. Xenogeneic stem cells come from a donor who belongs to a different species, such as a pig. Despite the fact that these cells should be rejected, their unique characteristics allow them to survive when injected into the body of another species. The ability of stem cells to differentiate into various tissues is their most well-known function, but they also possess other characteristics that can aid in healing.
