A blood stem cell can differentiate into only different types of blood cells. what kind of stem cell is this?

A: Multi potent

B: Totipotent

C: Pluripotent

D: Uni potent

A: Multi potent

Explanation:

In contrast to totipotent and pluripotent cells which can differentiate into and produce any structure of three germ layers (mesoderm, endoderm & ectoderm), a multipotent blood stem cell can differentiate into only different types of blood cells because it is specified and determined to produce only blood cells. In short, it can not differentiate into any other tissue like nervous tissue, epithelial tissue etc. The example of one such cell is hemocytoblast which gives rise to various type of blood cells like basophil, neutrophil, erythrocyte etc.

Also, unipotent cells can differentiate into one type of cell only. They have least potential to differentiate. These type of cells occur only in adult tissues not in early embryonic tissue.

Zygote is an example of totipotent cell while the cells of inner cell mass (ICM) are pluripotent.
