Dysmorphogenic Effects of First Trimester-Equivalent Ethanol Exposure in Mice: A Magnetic Resonance Microscopy-Based Study

Abstract

These results illustrate the teratogenic impact of maternal dietary EtOH intake occurring at time periods approximately equivalent to weeks 3 through 6 (GD 7 to 11 in mice) and weeks 7 through 12 (GD 12 to 16 in mice) of human gestation, further documenting EtOH's stage of exposure-dependent neuroteratogenic end points and highlighting the vulnerability of selected brain regions during the first trimester. Additionally they suggest that clinical attention should be paid to fetal hydrops as a likely component of FASD.
