As for its hair-related function, adiponectin appeared to have hair growth-promoting activity when added to human HF maintained ex vivo, exhibiting a notable increase in hair shaft length, i.e., 1.0 mm for adiponectin-treated HF compared to 0.8 mm for minoxidil-treated HF after 6 days of treatment. The gene discussed is ADIPOQ; the disease is hydrops fetalis.
