CellTalk #2 - Defining the terms that classify stem cells



man at blackboard
From CellTalk #1:


You learned that stem cells have the unique property to asymmetrically divide resulting in both differentiation and self renewal.

Stem cells are classified into the following categories: totipotent stem cells, pluripotent stem cells, multipotent stem cells and unipotent stem cells. Use the KEY to find your level of understanding as you explore basic terminology concerning potencies and stem cells.
