| Abstract: | Topographic distribution of dividing hepatocytes was studied in the liver lobule after hepatectomy performed at 10-11.30 a. m. The studies were conducted 20-32 h after surgery during the first increase in mitotic activity. It has been established that dividing hepatocytes appear simultaneously in all lobule areas, i. e. that all the hepatocytes are capable of responding to regenerating stimuli. However, further behaviour of dividing hepatocytes becomes different. It is concluded that hepatocytes from outer and intermediate lobule areas possess a more pronounced proliferative potential during peak mitotic activity after partial hepatectomy. |
