Fragments of renal carcinoma of the northern leopard frog, Rana pipiens, were cocultured in vitro with small pieces of tadpole heart, frog heart and frog kidney with gyrotory shaking for up to 14 days at 21°C and 28°C. No invasion by renal carcinoma occurred in confrontation cultures at 21°. However, the three normal tissues were invaded by renal carcinoma(More)
Fragments of Lucké renal adenocarcinoma were subjected to dissociation by rapid shaking after exposure to a divalent cation-free electrolyte solution, with or without 5 X 10(-4) M ethylenediaminetetraacetate (EDTA), at 7 degrees C and 28 degrees C. More cells detached at 28 degrees C than at 7 degrees C. Dissociation of cells from normal mesonephros(More)
