The objective of the present study was to characterize morphologically, morphometrically and stereologically the epithelial changes in the floor of the mouth of fetuses from rats that received all-trans-retinoic acid during pregnancy. The results suggest that all-trans-retinoic acid causes the appearance of malformed immature and less developed fetuses
