Regenerative medicine offers much promise for those suffering from several disease states. It is a method of using your own natural healing properties to assist in living a better quality of life. Stem cells are presently the largest target in the regenerative medicine arena.
Stem cells are naïve cells that have the ability to divide indefinitely. They may functionally change into any cell in our body and can integrate to the target tissue, either in the presence or absence of damage. (1) Stem cells may be isolated from several locations including the blastocyst, fetal tissue (various organs of such), umbilical cord blood/tissue and adult tissues (bone marrow, liver, fat, brain, muscle, and other tissues). There are various classifications of stem cells.
1. Totipotent, able to produce all embryonic and extra-embryonic tissue, i.e., all tissues that form us.
2. Pluripotent, which have the ability to change into any tissue from all three embryonic layers except placenta.
3. Multipotent, which have the ability to change into two or more different cell types.
4. Unipotent, only give rise to one cell type.
