What should we do in the order of stem cell?
Answers:
Well there are 2 major types of stem cells, pluripotent and multipotent.
Pluripotent cell have typically come from human embryos and can grow into anything in the human body, but this capacity for diversity cause a higher incidence of cancer as the tissue may continue changing. Further, embryonic cell and what they grow into are treated as a foreign body by the patient. Long term immune suppression is required lest the body reject the treatment.
Multipotent stem cells come from fully formed humans and are narrower within focus growing into a smaller selection by default, however, research has shown that human skin tissue can be coaxed into producing pluripotent cell just as embryonic stem cells. Any treatment that may derive from these pluripotent cells avoids the immune system conflict by using the patient's own tissue for treatment and the ethical dilemma of creating/destroying human natural life for medical purposes.
"The combination of four genes used to reprogram the skin cells regulate expression of downstream genes and either activate or silence their expression. The reprogrammed cell were not just functionally identical to embryonic stem cell. They also had identical biological structure, expressed the same genes and could be coaxed into giving rise to like cell types as human embryonic stem cells."

The solution then is to pursue both adult multipotent and developed pluripotent stem cell treatment as this promises both the fewest ethical issues and less risk to the patient. Source(s): http://en.wikipedia.org/wiki/Embryonic_s…
