Since stem cells and stem cell therapy have gained a lot of recent media attention, some of it contentious, I’ve decided to talk about stem cells in general, as well as some approaches to stem cell therapy, this month. Myrtle Beach stem cell therapy offers excellent info on this.
A stem cell is an undifferentiated cell that has the ability to self-renew and grow into at least three types of tissue. Embryonic stem cells can differentiate into any adult cell type and are formed from early stage embryos. Under a microscope, embryonic stem cells behave consistently, but when implanted into the body, they are much less predictable. They may have some research advantages, but their use is debatable, and they aren’t useful for actual treatments.
Post-fetal organisms have adult stem cells. Hematopoietic stem cells, which become red or white blood cells, or mesenchymal stem cells, which can become a variety of tissues such as bone, tendon, ligament, cartilage, heart, liver, or nerves, are examples of linage-committed stem cells. Bone marrow, fat, brain tissue, and muscles are all sources of adult stem cells. Fat produces the most mesenchymal stem cells in any tissue, while bone marrow and umbilical blood produce more stem cells that will become red or white blood cells.
Autologous, allogenic, and xenogenic stem cells are among the many types of stem cells. Autologous stem cells come from the same animal as the donor. These are the safest for transplanting since there is no risk of rejection. Allogenic stem cells come from a single species donor. Since stem cells lack the normal cell surface markers that activate immune responses, they can theoretically be used without fear of the host tissue rejecting them. Xenogenic stem cells are derived from a donor who is a member of a certain species, such as a pig. While one would expect these cells to be discarded, their specific characteristics allow them to live in the body of another species in some cases.
