Three kinds of stem cells related to regenerative medicine
Our body consists of about 6 trillion cells. Some of these cells have a short life span, while others have the ability to replenish the lost cells. Cells with this special ability are "stem cells".
1. ES cells
Stem cells cultured from fertilized eggs have the ability to transform into all cells. ※ Because the cells that should have developed into babies are used, there are ethical problems < P > 2. iPS cells < P > artificially add stem cells formed by specific genes to somatic cells such as skin, which have the same ability as ES cells. ※ Because it is a universal cell, there is a risk of differentiation into non-target cells.
3, adult stem cells
Stem cells taken from bone marrow and fat have the ability to differentiate into many different tissues and internal organs. Using the original autologous cells in the body, it is easy to be used in treatment. ※.
At present, the clinical application of regenerative medicine research is being developed all over the world. Recent studies have found many substances that may prolong life, and their application in clinical technology has been continuously developed.
