The 11.5, 12.5, 14.5, and 18.5 dpc murine livers were fixed and prepared for transmission electron microscopy. Scale bar = 1 μm. H indicates hepatoblasts (11.5, 12.5, and 14.5 dpc) or hepatocytes (18.5 dpc); hc, hematopoietic cells; I, Ito cells; S, sinusoid; arrowhead (14.5), bile canalicule; arrows (18.5), glycogen deposits.
