Abstract

The present invention describes a method for producing de novo papillae comprising the steps of a) providing isolated dermal papilla fibroblasts (DPF) from at least one dermal papilla (DP) from at least one hair follicle, b) providing isolated connective tissue sheath fibroblasts (CTSF) from at least one hair follicle and c) co-culturing the DPF with the CTSF under substantially non-adherent cell culture conditions to form spheroid cell aggregates.
