(PhysOrg.com) -- Most people consider hair as a purely cosmetic part of their lives. To others, it may help uncover one of nature`s best-kept secrets: the body`s ability to regenerate organs. Now, new research from Rockefeller University gets to the root of the problem, revealing that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide. The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.
