Definition
1. Stern cell “self-renews”, i.e. a stem cell undergoes cell division when it is called into action. While one daughter cell remains Stem cell , the other becomes more committed to forming a particular cell type (a “ committed progenitor”) by a process called “asymmetric division”.
2. Stem cell forms multiple cell types. i.e. “multipotent”
3. A single stem cell. when transplanted within the body.
completely “reforms” a particular tissue.
Stem cells have thus been long regarded as undifferent
iated cells capable of proliferation, self renewal, production
of a large number of differentiated progeny, and regeneration
of tissues (Hg. 1.6).
