TGF-B signaling in Neuroblastoma and Renal Cell Carcinoma
The tubular cells of the adult kidney are normally mitotically quiescent, in stark contrast to the massive regenerative capacity of the injured renal epithelium. In Paper I we characterized a new cell population of progenitor cells using ALDH as a selection marker. These cells are situated in the proximal tubular epithelium and are called proximal tubular progenitor cells (PTPCs). Gene expression
