Viability and morphology of human skin keratinocytes (KCs) after UVB exposure at an intensity of 27.5, 55, or 110 mJ/cm2. (a) Viability of cells was measured by using the XTT assay, and results were calculated as , using unpaired Student’s -test. (b) Morphology of the non-UVB-exposed cells and the cells cultured for 10 and 24 hr after UVB exposure at various intensities was observed by light microscopy and photographed at a magnification of 200x (scale bar: 100 μm).
