Given that Cd34-positive APs become negative for Cd34 as they differentiate into mature adipocytes [8], these data may support the notion that maternal obesity leads to an increased proliferation and presence of APs in the stromal vascular fraction of offspring gWAT, which, when offspring are exposed to a post-weaning HF diet, contribute to the enhanced adipogenic response to obesogenic nutritional stimuli in adulthood. This evidence concerns the gene CD34 and hydrops fetalis.
