Fig. 9.

Changes in a liver three days after a splanchnic division and 60 per cent hepatectomy experiment of group 8 as shown by light microscopy, electron microscopy and autoradiography. The hepatocytes on both sides of the liver are enlarged and contain normal amounts of rough endoplasmic reticulum, increased numbers of autophagosomes and lipid droplets and less glycogen than normal. The rate of cell division, as indicated by autoradiography, is higher on both sides of the liver than after splanchnic division alone and is particularly increased in the hormone influenced lobes, panel on left. Upper panels, hematoxylin and eosin, ×120; middle panels, electron micrography; ×1,700; and lower panels, autoradiography, ×300.
