裸鼠的胎盘和胎儿重量。

J Immunogenet. 1978 Jun;5(3):193-5. doi: 10.1111/j.1744-313x.1978.tb00645.x.

Placental and foetal weight and litter size were studied on the 18th day of pregnancy in the athymic nude mouse. Placental weight and litter size were unaffected by the absence of a thymus. Foetal weight was reduced, probably as a result of the health status of such animals.

在无胸腺裸鼠怀孕第18天时，对胎盘和胎儿重量以及窝仔数进行了研究。胎盘重量和窝仔数不受胸腺缺失的影响。胎儿重量减轻，这可能是由于此类动物的健康状况所致。
