In this week’s installment of UTMB’s Medical Discovery News, Norbert Herzog and David Niesel report that Japanese scientists recently discovered that when a gene called Sox21 is inhibited in mice, the rodents start losing hair two weeks after birth and are completely naked a week later. Turns out we humans also have the Sox21 gene. It’s found in human scalp tissue and in the outer layer of the hair. Though the study does not yet prove this gene is involved in human balding, it does increase knowledge of hair growth and retention and may help in developing treatments in the future.
