[Proliferation of adipose cells and their lipid accumulation in the rat at the perinatal stage; histoautoradiographic study].

After thymidine-3H injection into pregnant Rat, histoautoradiographic studies showed that adipose cell proliferation in different subcutaneous and visceral sites, was very important in Rat foetuses about 24 h before birth and that lipid accumulation in the labelled cells was very fast during perinatal 48 h.
