Fig. 7From: Effect of microbial siderophores on mammalian non-malignant and malignant cell linesEffect of Exo-MS on human cell lines K 562, MCF-7 and HEK 293. The results of MTT assay were plotted using statistical analytical software - GraphPad Prism 7.01 and SigmaStat 4.0. The readings of control wells containing untreated cells were considered as 100% survival. No statistically significant decrease in the percent survival was observed for (a) human leukemia cell K 562 at Exo-MS concentrations up to 0.5 mg/mL (b) breast cancer cell line MCF-7 at Exo-MS concentrations up to 1.0 mg/mL and (c) normal embryonic kidney cell line HEK 293 at Exo-MS concentrations up to 0.5 mg/mLBack to article page
