In response to these stimuli and according to the developmental state at the time of the injury, podocytes may react in different ways: (1) they can modify their phenotype and undergo foot process effacement, a phenomenon that is not associated with alteration of the number of podocytes per glomerulus; (2) they can undergo apoptosis, an event that may occur as result of intrinsic or extrinsic damage; (3) under certain circumstances, podocytes may undergo developmental arrest and resemble immature precursors, a phenomenon generally accompanied by mild proliferative activity; and (4) adult podocytes can dedifferentiate and reenter the cell cycle to actively proliferate and, under specific circumstances, express a dysregulated phenotype.
