Synthesis and Characterization of a New Collagen-Alginate Aerogel for Tissue Engineering

Figure 8

SEM of osteoblast cell culture at 48 h. (a, b) Cell attachment and cell proliferation can be observed over the collagen-alginate aerogel-based scaffold; osteoblasts seeded had a normal appearance with some filopodia extended to other cells. (c, d) Osteoblast cell culture at 48 h. Low cell attachment and low cell proliferation can be observed over the collagen-alginate-GO aerogel-based scaffold. Osteoblasts seeded had an abnormal appearance.
