This meeting, which focuses on pigment cell research, contains 2 lectures, 3 seminars and 30 abstracts in English. The lecture topics cover transdifferentiation in pigmented epithelial cells and the development and regeneration of thecentral nervous system by cross-interactions among transcriptional regulatorysignals. The seminar topics are the development of early melanoma and the involvement of cell senescence, apoptosis and p16, human melanocytes and the melanocortin 1 receptor gene and melanocyte proliferation and human skin differentiation in response to UV radiation. The abstract topics include hereditary melanoma, genetic mutations, skin changes during aging, melanocytes, keratinocytes and dendrites, gene expression, hair pigmentation, melanocytes stem cells cultivation from mouse vibrissal hair bulge, tyrosinase processing, opsin and transducin expression, Cushing's syndrome, eye development, Seborrheic keratosis, Lentigo senilis, Hermansky-Pudlak syndrome and Dyschromatosis Symmetrical Hereditaria.
