Summary
Hepatocytes were isolated by collagenasein vitro perfusion technique. Net glucose production in isolated hepatocytes obtained from fed, fasted and alloxan diabetic rats was studied. Net glucose production from alanine, pyruvate and fructose was increased by 2–5 fold in isolated hepatocytes obtained from fasted and alloxan diabetic rats. Similar increases in the incorporation of14C-bicarbonate into glucose was also observed. Net glucose production in isolated hepatocytes was also compared to otherin vitro preparations. Net glucose production was much higher (2–5 fold) in isolated hepatocytes than that reported previously for liver slices or perfused liver. Studies on glycogen and protein synthesis show a 2 fold stimulation in the incorporation of U-14C-glucose into glycogen and U-14C-leucine into protein by the addition of 100 µU of insulin to isolated hepatocytes.
