The ultimate stem cell is the fertilized egg from which we came. This omnipotent stem cell divides countless times, “differentiates”, and forms more and more specialized tissues, and our body is the eventual result. All of our tissues contain some stem cells, which grow increasingly rare as we age.
Regenerative medicine takes advantage of stem cells derived from diverse sources. An embryo, an umbilical cord, or your bone marrow contains stem cells. Even one of your mature connective tissue cells that has been dedifferentiated, or sent back along the pathway that originated from the single cell from which you came, can be induced to form a stem cell (iSC).
If the stem cell originates from your own tissues, it is accepted by your body, as one of its own.
I have an wealthy acquaintance whose Parkinson’s disease is being treated by one of his own cells induced to form a dopamine containing neuronal stem cell.
The article posted previously regarding rotator cuff surgery apparently used stem cells to shorten the recovery time.
I have heard about the use of stem cells in heart failure, osteoarthritis, and other joint problems, and I’m sure we will hear about this increasingly as time passes. However, there are hurdles to be overcome, moral, legal and medical. The possibility (small) of induced stem cells to evolve into cancer is one medical hurdle, and if the Stem Sell originates from another individual, immunosuppressive treatment must be used in the recipient to allow the stem cells to work. Also, the use of the other individual’s stem cells may involve some moral, legal and possibly religious objections.
