Fig. 7From: Cytotoxic, apoptotic, and genetic evaluations of Nigella sativa essential oil nanoemulsion against human hepatocellular carcinoma cell linesApoptotic graphs showing the un-apoptotic cells (a top) and apoptotic cells (b bottom) of N. sativa essential oil (F0) and its nanoemulsions (F1 and F2) against hepatocellular carcinoma cell lines HepG2 and Huh-7 in comparison to normal WI-38 cells. Control: untreated cells. Bars represent average of 3 replicates ± SD. *Statistically significant decrease of treated cancer cells compared to control (P < 0.05). #High statistically significant decrease of treated cancer cells compared to control (P < 0.01). @Non-significant change of treated WI-38 cells compared to control (P > 0.05).Back to article page
