The epidermal expression of the vascular endothelial growth factor A (VEGF‐A; Detmar, 1996) induces perifollicular angiogenesis and sustains HF growth; conversely, inhibition of VEGF‐A leads to a delay in HF growth accompanied by reductions in HF size and perifollicular vascularization (Yano et al, 2001). Here, VEGFA is linked to hydrops fetalis.
