  • Title: Stem cells and kidney disease.
    Author: Hishikawa K, Fujita T.
    Journal: Hypertens Res; 2006 Oct; 29(10):745-9. PubMed ID: 17283860.
    Abstract:
    Functional recovery in acute renal failure is well known, and the adult kidney is generally recognized to have the capacity to regenerate and repair. Several groups have reported the contribution of bone marrow-derived cells in this process, and others have confirmed the existence of adult stem cells in the kidney, including slow-cycling cells, side population cells, CD133+ cells and rKS56 cells. However, recent data demonstrated that in vivo differentiation of bone marrow-derived cells into renal tubular cells may not occur at all, or is at most a minor component of the repair process. Moreover, it is now generally accepted that stem cells and multipotent cells contribute to the regenerative process by producing protective and regenerative factors rather than by directly differentiating to replace damaged cells. Therefore, for clinical regenerative medicine in kidney disease, the focus of stem cell biology will shift from multiple differentiation of cells or cell-therapy to multiple functions of the cells, such as the production of bone morphologic protein-7 and other regenerative factors.
