Official Title: A Comparative Study Between Autologous Non Cultured Epidermal Cell Suspension Versus Combination of Autologous Non Cultured Epidermal Cell Suspension and Non Cultured Dermal Cell Suspension in Stable
Brief Summary:
Vitiligo is a complex disease causing a selective, often progressive, loss of functioning melanocytes from epidermal basal layer resulting in white patches on the skin and occasionally mucosae. Worldwide prevalence of vitiligo is around 1% whereas in India it is around 3-4% ranging from 0.46% to 8.8%.
Etiopathogenesis of vitiligo is multifactorial consisting of genetic, immunological and environmental factors. Environmental and genetic factors act in concert to destroy melanocytes. Reactive oxygen species (ROS) play important roles in vitiligo pathology,but the autoimmune pathogenesis has been proposed as one of the main causes of vitiligo.
Surgical methods, mainly transplantation of non cultured epidermal cell suspension are effective treatment for stable vitiligo. Transplantation of autologous noncultured epidermal cell suspension and non-cultured dermal cell suspension in combination (a mode of cellular grafting technique) is a novel surgical method for the treatment of vitiligo. Cytotoxic CD8+ ( cluster of differentiation 8+) cells in vitiligo perilesions may dictate the fate of transplantation, and strategies against CD8+ T cell activation might be beneficial for patients undergoing melanocyte transplantation. Mesenchymal cells could inhibit T cell proliferation and induce T cell apoptosis. Bartsch first identified and characterized dermal mesenchymal cells (DMCs). They have a multi-lineage differentiation potential into adipocytes, osteocytes and chondrocytes.Vitiligo patients' autologous melanocytes transplantation efficiency may be predicted by perilesional skin-homing CD8+ T cell activities, and the immunoregulatory DMCs might be used as auxiliary agent to improve the efficacy.
This pilot study is planned to compare transplantation of autologous noncultured epiderm
