Stem cells bring fast direct improvement, without differentiation, in acute renal failure

Acute renal failure, or ARF, is as serious as it sounds. An estimated 40% of critical care hospital admissions experience ARF. Estimates of their death rate range from 50% to 80%, complicated by the fact that patients with ARF often simultaneously suffer failure of other major organ systems. The ...
