Activation of caspase-3 in response of cell exposure to GPS. Confocal microscopic examination of CCRF-CEM cells exposed to 3 puffs GPS for the activation of caspase-3. First row: FITC-staining (green), second row: PI counterstain (red), third row: superimposed FITC/PI images. A-C) untreated cells, D-F) cells treated with 2 μM staurosporine, G-I) cells harvested at 4 hr post-exposure, J-L ) cells harvested at 24 hr post-exposure. Scale bar = 10 μm.
