Regeneration of collagen fibrils at the papillary dermis by reconstructing basement membrane at the dermal–epidermal junction
The epidermal basement membrane deteriorates with aging. We previously reported that basementmembrane reconstruction not only serves to maintain epidermal stem/progenitor cells in the epidermis, but also increases collagen fibrils in the papillary dermis. Here, we investigated the mechanism of the latter action. Collagen fibrils in the papillary dermis were increased in organotypic human skin culture […]
