Pigmentation and inhibition of wound contraction by cultured skin substitutes with adult melanocytes after transplantation to athymic mice.
Wound closure with cultured skin substitutes results in epithelium that is consistently hypopigmented. Hypothetically, addition of human melanocytes to cultured skin grafts may result in normal pigmentation of healed skin. Skin substitutes were composed of human epidermal keratinocytes and melanocytes, dermal fibroblasts, and collagen-glycosaminoglycan substrates, and were incubated for 12 d in...
متن کاملTumorigenicity Testing in Athymic Mice of Cultured Human Melanocytes for Transplantation in Engineered Skin Substitutes.
Autologous engineered skin substitutes (ESS) have been shown to close excised, full-thickness burns, but are consistently hypopigmented due to depletion of human melanocytes (hM) during culture of keratinocytes. Hypothetically, addition of hM to ESS may restore uniform pigmentation, but may also promote neoplasia and tumor formation. To evaluate this risk, 16 strains of hM were isolated and pro...
متن کاملCultured skin substitutes: a review.
Skin substitutes composed of cultured cells and biopolymers provide alternative materials for study of skin biology and pathology, treatment of skin wounds, safety testing of consumer products, and therapeutic delivery of gene products. Most frequently, substitutes for epidermis consist of cultured keratinocytes and dermal substitutes consist of resorbable biopolymers populated with cultured fi...

The regulation of skin pigmentation.
Visible pigmentation of the skin, hair, and eyes depends primarily on the functions of melanocytes, a very minor population of cells that specialize in the synthesis and distribution of the pigmented biopolymer melanin. Melanocytes are derived from precursor cells (called melanoblasts) during embryological development, and melanoblasts destined for the skin originate from the neural crest. The ...
