The gene list contains LEPR, WNT5A, PRDM1, HOXC8, FGFR2, BMP4, LTBP1, and PTGFR. They almost participate in all pivotal aspects of DPCs functions in HF cycling, such as HFSCs activation, hair matrix cells (HMCs) proliferation and differentiation, angiogenesis, and hormone-mediated hair growth regulation. This evidence concerns the gene BMP4 and hydrops fetalis.
