The main difference between cancer cells and normal tissue stem cells is that cancer cells are abnormal and present mutations.
In this review, we propose that one of the differences between normal stem cells and cancer stem cells is their degree of dependence on the stem cell niche, a specialized microenvironment in which stem cells reside.he stem cell niche is composed of a group of cells in a special location that functions to maintain stem cells. The niche is a physical anchoring site for stem cells, and adhesion molecules are involved in the interaction between stem cells and the niche and between stem cells and the extracellular matrix.
