EPITHELIAL OUTGROWTHS FROM TISSUE CULTURES OF BASAL CELL EPITHELIOMAS

[摘要] In two series of epithelial cells, these sheets grew out in a liquefaction pool rimmed by fibroblastic cells oriented circum-ferentially and then extending in a radial pattern. While it seems likely that the epithelial cells represent in vitro proliferations of the epithelial component of the basal cell epitheliomas, it is possible that they are outgrowths of normal adnexal structures present in the biopsy explants. Reasons are given why it is thought that the sheets of epithelial cells arise from the tumor tissue.
