Fig. 2From: Cancer-associated fibroblasts promote the survival of irradiated nasopharyngeal carcinoma cells via the NF-κB pathwayCAFs secreted higher level of IL-8 than NFs. a and b CAFs promoted survival of NPC cells after irradiation. c and d Higher level of IL-8 were detected in the CAF supernatants and evaluated by real-time PCR. e and f Represented Immunofluorescence images of IL-8 and α-SMA in NPC tissues were shown. g and h Treatment with an IL-8 receptor antagonist (10 μM) inhibited the proliferation of NPC cells after irradiation. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001, ns, no significanceBack to article page
