Fig. 2From: Isolation and characterization of three new anti-proliferative Sesquiterpenes from Polygonum barbatum and their mechanism via apoptotic pathwayPhase contrast microscopic images of NCI-H460 cells after treatment with compound 3 at 20 and 40 μM concentrations. In control well, the cells were in their normal morphology while treated cells died and escaped the monolayer after 24 h of the treatment. The images were taken at 10X magnificationBack to article page
