Screening of potential reproductive toxicants by use of porcine granulosa cell cultures.

Journal Article (Journal Article)

While approximately 60 000 chemicals are in widespread use with 1000 new chemicals introduced into the environment each year, the biologic effects of these agents are poorly understood. With the specific goal of testing for potential reproductive toxicity, we have established methodology for the screening of compounds in vitro by measuring effects on progesterone production by porcine granulosa cells in culture. Granulosa cells were harvested by mechanical agitation, cryopreserved, and cells with known progesterone production capacity utilized for culture. Agents to be tested were added to cultures of 10(5) cells and the media assayed for progesterone by radioimmunoassay. Estradiol suppression of progesterone production was easily demonstrated in this system and utilized as a verification of responsiveness. The pesticide o,p-DDT and its isomer p,p-DDT produced dramatic suppression of progesterone production apparently with equal potencies to estradiol. By contrast, the pesticides malathion, parathion and dieldrin and the fungicide hexachlorobenzene were without effect in this test system.
