Fig. 2From: Molecular mechanism of cardol, isolated from Trigona incisa stingless bee propolis, induced apoptosis in the SW620 human colorectal cancer cell lineMorphology of SW620 cells at 72 h after treatment with cardol at 0 μg/mL (control), 8 and 14 μg/mL, or doxorubicin at 0.5 μg/mL. Images are at 400 x magnification and are representative of those seen from at least three such fields of view per sample and three independent repeats. Scale bar = 50 μmBack to article page
