Fig. 4From: Effect of liposomal celecoxib on proliferation of colon cancer cell and inhibition of DMBA-induced tumor in rat modela Cell cycle analysis of HCT 15 cells treated with control (PBS), celecoxib (IC50), empty liposomes (equivalent to volume of liposomal celecoxib), and liposomal celecoxib (IC50) for 48 h. M1-Sub-G1 Phase, M2-G0/G1 Phase, M3-S Phase, and M4-G2/M Phase. b DAPI nuclear staining of HCT 15 cells treated with control, free celecoxib (IC50), empty liposomes (equivalent to volume of liposomal celecoxib), and liposomal celecoxib (IC50) for 48 h (epi-fluorescence microscopic image at ×20 and scale bars, 10 μm). DNA fragmentation and apoptosis are marked with arrowsBack to article page
