New Prostrates Grown From Single Stem Cell
Date:10/22/2008

t in other cells, making differentiation difficult.

The authors of this paper found a new marker, CD117, which, when combined with previously known prostate stem cell cancer markers, could identify a single, normal prostate stem cell.

That single stem cell was able to generate functional prostates and was also capable of renewing itself.

"We are trying to first define what is the normal cell compartment that can generate a tissue," Johnson explained. "Once we have that knowledge, is it that compartment that goes awry when cancer initiates? What is the resistant population, and what is regenerating a tumor? Is it the same cell responsible for generating normal tissue?" she said.
