Isolated cells of the eel liver were prepared from the liver perfused by the medium containing collagenase. Cells isolated by this method were undamaged when viewed with light microscopy; the viability of the cells was 85 to 90%, as judged by staining with 0.02% trypan blue. Adrenalin at 10-4M promoted glycogenolysis in isolated cells, while insulin at 5×10-5M significantly inhibited it. These cells actively incorporated 14C-pyruvate or 14C-lactate into glucose. Amino-oxyacetate (0.5mM) inhibited 14C-glucose synthesis not only from 14C-lactate but also from 14C-pyruvate. Respiratory inhibitors such as methylene blue (5×10-3mM), KCN (1mM), and 2, 4-dinitrophenol (0.5mM) inhibited 14C-glucose synthesis from 14C-pyruvate by 58, 86, and 100% respectively.
