ANPEP and alopecia: Our previous studies found that adiponectin protein (APN) promotes hair growth ex vivo effectively, along with inducing mRNA expressions of key hair growth factors, including insulin‐like growth factor 1 (IGF‐1), vascular endothelial growth factor (VEGF), and hepatocyte growth factor (HGF), which suggests that APN is a promising molecule to treat alopecia (Won et al, 2012).
