The objective of this study was to assess whether nucleotides supplementation in vitro could suppress ethanol-induced developmental toxicity in mouse. The models of whole embryo culture (WEC) and midbrain (MB) cell micromass culture were used in this study. In WEC system, exposure to 4.0 mg/mL ethanol for 48 h yielded various developmental malformations of the mice embryos. Nucleotides supplementation (0.16, 0.80, 4.00, 20.00, and 100.00 mg/L) improved the growth parameters to some extent, and the protective effects peaked at 4.00 mg/L. In MB cell micromass culture system, exposure to 4.0 mg/mL ethanol for 5 days resulted in suppression of proliferation and differentiation. Supplementation of nucleotides (0.16, 0.80, 4.00, 20.00, and 100.00 mg/L) showed some protective effects, which peaked at 4.00 mg/L, too. The present research indicated that nucleotides supplementation might be of some benefit in the prevention of ethanol-induced birth defects; however, appropriate dosage requires attention.
