FIG. 8.

X-ray and microcomputed tomography (μ-CT) images of MC3T3-E1 osteoblasts cultured on NF-Gelatin and NF-Gelatin-NCP scaffolds for 3 weeks in vitro. (a) Representative X-ray image of the NF-Gelatin group; (b) Representative X-ray image of the NF-Gelatin-NCP group; (c) Representative μ-CT image of the NF-Gelatin group; (d) Representative μ-CT image of the NF-Gelatin-NCP group. The X-ray and μ-CT images clearly show that more minerals secreted from the osteoblasts were deposited on the NF-Gelatin-NCPs than on the NF-Gelatin, and the deposited minerals were distributed evenly throughout the entire NF-Gelatin-NCPs.
