Effects of Composition of Iron-Cross-Linked Alginate Hydrogels for Cultivation of Human Dermal Fibroblasts

Figure 5

Proliferation of NHDF on Fe-alginate film under stable gel conditions. Cells were seeded onto high-G (a–c) and high-M (d–f) alginate films that had been immersed in culture medium for 8 days to stabilize the gel properties. Phase-contrast micrographs were taken at 1 day (a, d), 5 days (b, e), and 8 days (c, f) after cell seeding. Bar equals 200 μm. The numbers of attached cells on the films were counted after incubation for 8 days (g).
