To study human skin pigmentation in a physiological in vitro model, we developed a pigmented reconstructed skin reproducing the three-dimensional architecture of the melanocyte environment and the interactions of melanocyte with its cellular partners, keratinocytes, and fibroblasts. Co-seeding melanocytes and keratinocytes onto a fibroblast-populated(More)
Xeroderma pigmentosum (XP) is a devastating disease associated with dramatic skin cancer proneness. XP cells are deficient in nucleotide excision repair (NER) of bulky DNA adducts including ultraviolet (UV)-induced mutagenic lesions. Approaches of corrective gene transfer in NER-deficient keratinocyte stem cells hold great hope for the long-term treatment(More)
To study cutaneous pigmentation in a physiological context, we have previously developed a functional pigmented reconstructed skin model composed of a melanocyte-containing epidermis grown on a dermal equivalent comprising living fibroblasts. The present studies, using the same model, aimed to demonstrate that dermal fibroblasts influence skin pigmentation(More)
