Multiple genes provide a link between kidney progenitor cells
August 14th, 2006
According to research from Israel, multiple imprinted and sternness genes provide a link between normal and tumor progenitor cells of the developing human kidney. "Wilms' tumor (WT), the embryonic kidney malignancy, is suggested to evolve from a progenitor cell population of uninduced metanephric blastema, which typically gives rise to nephrons. However, apart from blastema, WT specimens frequently contain cells that have differentiated into renal tubular or stromal phenotypes, complicating their analysis. "We aimed to define tumor-progenitor genes that function in normal kidney development using WT xenografts (WISH-WT), in which the blastema...
