Explanation:
Detailed explanation-1: -They have the ability to renew themselves and differentiate into specialized cell types. While ESCs can become all cell types, adult stem cells are limited to differentiating into distinct cell types of their tissue of origin, and they are therefore multipotent or unipotent stem cells.
Detailed explanation-2: -Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord.
Detailed explanation-3: -There are 2 major classes of stem cells: pluripotent cells, which can become any cell in the adult body, and multipotent cells, which are restricted to becoming a more limited population of cells.
