The kidney possesses an impressive regeneration capacity and is the most performant among all tissues in the body. Yet ischaemic injury to the kidney produces acute tubular necrosis and apoptosis followed by tubular regeneration and recovery of renal function. Although mitotic cells are present in the tubules of postischaemic kidneys, the origins of the proliferating cells were considered until recently as the result of this regeneration capacity of the kidney, whereby the surviving remaining tubular cells start proliferating and migrating along the denuded basement membrane.
In both humans and mice, the proof-of-principle clinical observation has been obtained in support of the ability of cells emanating from the bone marrow (BM) to become renal epithelial cells. Several groups have reported the presence of Y-chromosome-positive renal tubular cells in kidneys of male recipients who received a renal transplant
