Fig. 2From: Iron oxide polyaniline-coated nanoparticles modulate tumor microenvironment in breast cancer: an in vitro study on the reprogramming of tumor-associated macrophagesIn a Frequency of MCF-7 cells expressing active caspase 3/7 after 24 h of co-culture and labeled with Sytox after 24 h and 48 h of co-culture. In b Frequency of MDA-MB-231 cells expressing active caspase 3/7 and labeled with Sytox after 24 h and 48 h of co-culture. The data are presented as mean ± standard deviation and represent three independent experiments. Statistical analysis was performed using paired t-test. (*) p < 0.05 compared to the unstimulated tumor cell. (Bar) p < 0.05 between co-cultures of tumor cells and macrophages exposed and unexposed to NPs, p-value indicated in the graph.
