title: [Interspecies somatic hybrid cultures from human epidermal cells and 3T3-4E mouse fibroblasts].
abstract: Interspecific somatic hybrids were obtained by fusion of adult human epidermal cells with Mouse fibroblasts 3T3-4E, deficient in thymidine kinase. These hybrids were identified by their morphology and by the presence of markers from the parental cells. Some characters of keratinocytes such as keratin subunits 50 and 51 K were present in primary cultures and disappeared after serial passages, whereas bullous pemphigoid basement membrane zone antigens persisted for at least 20 passages. At the 7th passage, a metacentric chromosome, and more often a submetacentric chromosome, presumably of human origin, were observed in some cells.
