Figure 4From: Expression and localization of P1 promoter-driven hepatocyte nuclear factor-4α (HNF4α) isoforms in human and ratsImmunoelectron microscopic detection of HNF4α in rat hepatocytes and renal tubules. Rat liver and proximal tubules of kidney were immunostained with K9218 and examined by electron microscope. Immunoelectron microscopy indicates a dense HNF4α nuclear distribution in hepatocytes (B and E) and proximal tubules (C and F). A and D; Negative control.
