Continuous-perifusion tissue culture of fetal and adult pancreas of the lizard Anolis carolinensis.
The differentiation of the fetal saurian pancreas in continuous-perifusion tissue culture (CPTC) was examined. Splenic pancreases from 24-day postoviposition fetuses of the green anole, Anolis carolinensis, were grown for 8 to 31 days by CPTC following successful preliminary studies with adult pancreas. Adult anolian endocrine pancreas was maintained by up to 7 days by CPTC. The pancreatic explants were examined morphologically by light and electron microscopy. The functional integrity of the endocrine cells was evaluated by measuring hormone levels of the explants and in the basal medium and by determining the kinetics of hormone release. The pancreatic endocrine cells from fetal and adult anoles were functionally and morphologically intact after CPTC. The exocrine pancreas was not maintained during cultures. This study demonstrates for the first time the growth of the reptilian endocrine pancreas in culture.
