Figure 4: Osteoblasts’ cell morphology on different scaffolds. SEM micrographs of osteoblasts seeded on different scaffolds and cultured for one week. (a) Osteoblasts seeded on bovine bone scaffold after seven days of culture at 3,000x. Cytoplasmic processes of osteoblast-substrate interactions and cell adhesion with filopodia and lamellipodia. (b) Osteoblasts seeded on bovine bone scaffold after seven days of culture at 1,500x. (c) Osteoblasts seeded on a HA scaffold after seven days in culture at 3,000x. (d) Osteoblasts seeded on a porous silicon scaffold after seven days of culture at 800x. Osteoblasts spreading on surface with filopodia in the substrate contact.
