Osteoconductivity and Biodegradability of Collagen Scaffold Coated with Nano-β-TCP and Fibroblast Growth Factor 2
Figure 4
(a) CCK-8 assays of MC3T3-E1 cell proliferation after 24 and 48 h incubation (, mean ± SD). Ctrl, Col, and TCP indicate control, collagen sponge, and nano-β-TCP/collagen scaffold, respectively. . (b) SEM micrograph of MC3T3-E1 cells seeded on the nano β-TCP/collagen scaffold after 24 h incubation. Cell spreading is shown on the scaffold (arrows). Scale bar represents 10 μm (b).
