Chapter 19, Problem 4U
Summary Introduction
Introduction:
There are certain cells in an organism’s body that are undifferentiated. These cells can give rise to different cell lines based on where they are found. However, their potency (degree of undetermined-ness) differs. Some stem cells can give rise to only a single type of cell (unipotent) and some can give different cells (multipotent).
