Teratogenic effects of excess glucose on head-fold rat embryos in culture.
Rat embryos explanted at nine and one-half days of gestation (early head-fold stages) were cultured for 48 hours in rotating bottles containing rat serum and a gas phase. Addition of 12-15 mg/ml of D-glucose to the culture medium resulted in severe abnormalities and retarded development in a high proportion of embryos, whether or not the osmolarity increase brought about by the addition of glucose was corrected. The raised osmolarity, however, increased the frequency and severity of malformations observed. L-glucose produced no abnormalities, though embryonic development was retarded.
