Peroxisome proliferator-activated receptor-γ is essential in the pathogenesis of gastric carcinoma

Figure 4 Morphological changes of MGC803 cells 24 h after treatment with 30 μmol/L 15d-PGJ₂. Cell shapes were observed by fluorescence microscopy (Hoechst 33342 staining, × 400). Nuclear chromatin condensation, marginalization of nuclear chromatin and half moon formation, nuclear fragments with bright chromatin and apoptotic bodies were easily identified in some cells.
