Kidney repair from injury is a major focus of interest for research, both clinical and basic, in the field of acute renal failure. This is so because very little progress has been made during the past several years to improve mortality in hospitalized patients with acute renal failure despite the unique potential of the kidney for complete structural and functional recovery. Novel therapeutic options have recently emerged from the knowledge of molecular mechanisms of tissue injury after ischemia, including pathways of endothelial-leukocyte interaction and epithelial cell aggregation mediated by integrin molecules. These strategies are promising because they may target early mechanisms of leukocyte infiltration and tubular obstruction. However, it seems clear that additional interventions should address the reparative program that potentially leads to the full restoration of kidney structure and function. Thus, acceleration of repair from acute renal failure is achieved experimentally by growth factors which besides different renal actions seem to have in common the ability to stimulate proliferation of surviving tubular epithelial cells. We direct attention to cellular processes which characterize, and possibly have role in, renal repair from acute tabular injury as potential targets of therapy. In addition to proliferation, they include epithelial differentiation and apoptosis. Further investigation in the biology of repair should set the stage for rational design of targeted therapies which may accelerate the pace of recovery and hopefully decrease mortality in such a dramatic and potentially reversible setting.
