In order to study the in vitro embryotoxicity and dysmorphogenesis of water insoluble compounds, solvents or chemical delivery systems of low toxicity and teratogenicity to the developing embryo must be found. Therefore, day 10.5 rat embryos were cultured for 2 days in whole rat serum containing 0.1, 0.5 and 2.5 vol.% of ethyl alcohol, dimethysulfoxide, acetone, Tween 80, corn oil and 10% acetone/90% corn oil. No adverse effects occurred with any of the solvents at the 0.1% concentration level. At 0.5% ethyl alcohol and Tween 80 significantly reduced embryonic growth and increased the incidence of embryonic abnormalities. With the exception of corn oil and acetone/corn oil, embryos cultured in media containing 2.5% of various solvents failed to grow, did not differentiate, and died during the culture period. Corn oil suspended in rat serum by use of ultrasound was non-toxic even at concentrations of 2.5% and 10%.
