NRP1 and squamous cell carcinoma: In addition, HT1080 fibrosarcoma and A431 epidermoid carcinoma cells likewise expressed both NRP1 and MET (Figures 5A, 5F, 6A; Supplementary Figure 7B) especially under chemically induced hypoxia (Figure 5C, 5D, Supplementary Figure 6), thus being potential targets of rhodocetin-αβ as well.
