用未孕小鼠观察了品系、生殖条件和胎盘供体品系对胎盘吞噬的影响。将C57 BL/6 By和BALB/cBy品系的小鼠在没有先前分娩经验、一次分娩经验而没有护理经验或一次分娩经验而有护理经验之后暴露于任一品系的胎盘。不同品系间差异显著，不同繁殖条件间差异显著，不同胎盘供体品系间差异不显著。菌株与繁殖条件之间存在显著的交互作用，而与胎盘菌株之间无显著的交互作用。据推断，小鼠在分娩期间和分娩后获得和利用相关刺激的能力，以产生从与分娩相关的生理控制中解放胎盘吞噬的能力，受到基因型的影响。
The effects on placentophagia of strain, reproductive condition, and strain of placenta donor were observed in nonpregnant mice. Mice of the C57BL/6By and BALB/cBy strains were exposed to placentas of either strain after either no previous parturitional experience, one parturitional experience without nursing experience, or one parturitional experience with nursing experience. There was a significant effect of strain, a significant effect of reproductive condition, but no significant effect of strain of placenta donor. There was a significant interaction between strain and reproductive condition, but no significant interactions with placenta strain. It was inferred that the ability of a mouse to acquire and utilize relevant stimuli during and after parturition, in order to produce an emancipation of placentophagia from the physiological controls associated with parturition, is influenced by genotype.
