Abstract |
The effect of NBM incorporation in PLA nanofibers on their mechanical properties and the differentiation and mineralization of osteoblasts was studied. At 20% NBM, the Young's modulus of the nanofibers was 37.78 +/- 4.23, significantly larger than that of pure PLA nanofibers. MC3T3-E1 pre-osteoblasts attached to both types of nanofibers and developed full osteogenic phenotypes. A profound effect of NBM on the mineralization of MC3T3-E1 pre-osteoblasts was confirmed, suggesting that NBM/PLA composite nanofibers exhibit properties similar to those of the native collagen-rich mineralized bone matrix, and could therefore serve as a temporary substrate for facilitating the differentiation and mineralization of bone-forming cells.
