Fetal mouse salivary glands and applications for determining teratogenic mechanisms in vitro.
Culture systems offer advantages for studying the actions of chemicals on mechanisms of development. Growth, [3H]thymidine incorporation, and 14C-amino acid incorporation were measured to determine culture conditions and the response of glands to three chemicals. Eagle's MEM supported the best growth and the best time for double isotope presence was the second 24 h of culture. Cyclamate had no effect on growth or isotope incorporation but cycloheximide disturbed 14C more than 3H. 5-Azacytidine was toxic but the incorporation of both isotopes exhibited the same pattern.
