In recent years there have scientists researching more about the kidney and its regenerative, or lack there of, abilities. Some scientists have found that the kidney can regenerate damaged portions of itself through cellular repair. Bone marrow-derived cells (BMDC) have been found to migrate to the kidney, proliferate and transdifferentiate into the certain cells needed to repair the kidney (Little). They differentiate into tubular epithelial cells that rebuild the structure of the kidney (Little). Mesangial cells are also produced by the BMDCs and create the smooth tissues around the blood vessels in the kidney (Little). The surrounding good cells have also been shown to contribute to the regenerative process in acute damaged areas by proliferating and increasing the kidney mass. This type of repair allows the kidney to be scar-free and work properly, although if there is chronic injury the damage will turn into scarring and functional loss that cannot be undone.
