As illustrated in Figure 3B, IL1β-stimulated NCF-CM stimulated proliferation of all the tumor cells tested (dark grey bars, left vertical axis in Figure 3B) but also promoted the viability of CRC cell lines exposed at fixed doses of L-OHP (dark grey bars, right vertical axis, Figure 3B; significant P values correspond to adjusted P values after Dunn’s multiple comparison test). Here, IL1B is linked to colorectal carcinoma.
