Explanation;
-Multipotent cells are those cells that can develop into more than one cell type, however, they are more limited than pluripotent cells. Adult stem cells and cord blood stem cells are considered multipotent.
Totipotent cells on the other hand, are those cells that can form all the cell types in a body, together with the extraembryonic, or placental cells. Embryonic cells are the only cells that are totipotent within the first couple of cell divisions after fertilization.
Pluripotent cells are those cells that give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.
