Abstract
Monitoring hepatocyte proliferation in situ following partial hepatectomy is widely used to characterize cytokines, growth factors and signaling molecules and pathways as well as the regulatory mechanisms involved in liver regeneration. Periodic measurement of the liver/body mass ratio estimates the rate of liver regeneration, which is often supplemented by evaluating the proportion of proliferating hepatocytes using a synthetic nucleoside analog such as 5-bromo-2'-deoxyuridine (BrdU) or the nuclear accumulation of proliferating cell nuclear antigen (PCNA) in proliferating cells. The introduction of the thymidine analog 5-ethynyl-2’deoxyuridine (EdU) and its detection by “click chemistry” using fluorescently labeled reagents has simplified the evaluation of live cell proliferation as it eliminates certain limitations of antibody-mediated detection of BrdU. Here, we describe the EdU-based measurement of hepatocyte proliferation during liver regeneration and correlate the results with that of Ki67 and PCNA-based assays.
