Research on the Structure of Fish Collagen Nanofibers Influenced Cell Growth

Figure 4

MTT assays for proliferation of HEK-293 cells co-cultured with fish collagen at 1, 3, 5, 7 days (Control indicate co-cultured without materials; I indicate 𝑣=0.1 mL/h; II indicate 𝑣=0.5 mL/h; III indicate 𝑣=1.0 mL/h; IV indicate 𝑣=1.5 mL/h).
