A Study to Evaluate and Compare Injections of Autologous Dermal and Epidermal Cells Into the Balding Scalp of Subjects With Hair Loss (CA-0004669)

A piece of occipital scalp, plucked of hairs prior to excision, is taken from the subject. The epidermal and dermal cells from this tissue are expanded in culture. The cells are then harvested and, for certain types of product, combined. The cells are then injected into the balding area of the scalp of the original subject.
