Changes in dry weight and projected area of human epidermal cells undergoing keratinization as determined by scanning interference microscopy.
Cells, obtained from human leg by successive treatments with trypsin, were air dried on microscope slides before mounting in glycerol. Dry weights and projected areas of individual cells were measured using a Vickers M 86 scanning microinterferometer. The dry weights of cells varied from 100 pg for basal cells to 700 pg for large squames. Corresponding projected areas varied from 100 to 1500 mum2.
