Comparative studies on in vitro mitogen-induced proliferation of peripheral blood lymphocytes in dog and breeding fox.
In vitro blastogenesis of dog and fox lymphocytes was compared by a microculture technique. The highest 3H-thymidine incorporation in cultures of dog lymphocytes was observed at day 3, while in those of fox at day 2, incubated either at 37 degrees C or at 39 degrees C. Lymphocytes cultured at 39 degrees C incorporated more tritiated thymidine than did cells cultured at 37 degrees C. The stimulation index (SI) of dog peripheral blood lymphocytes to both mitogens concanavalin A (Con A) and leucoagglutinin (LA) was in a similar range, while pokeweed mitogen (PWM) showed a weaker but significant stimulatory action. The blastogenesis of fox lymphocytes was the greatest in Con A stimulated cultures. The mitogenic potency of LA and PWM was about half of that of Con A, with no essential difference between them. Maximum lymphocyte proliferation of dog and fox was observed when culture media were supplemented with 10% fetal calf serum (FCS).
