Osteogenesis of Human iPSC-Derived MSCs by PLLA/SF Nanofiber Scaffolds Loaded with Extracellular Matrix

Figure 2

(a) SEM images of PLLA/SF nanofibrous scaffolds with the different mass ratios including 100/0, 70/30, 50/50, 300/70, and 0/100. (b) The diameter distributions of PLLA/SF nanofibrous scaffolds with the different mass ratios were investigated. MD, mean diameter. (c) Fourier transmission infrared spectrum (FTIR) of different mass ratios of PLLA/SF nanofibrous scaffolds. A, pure PLLA; B, PLLA/SF = 70/30; C, PLLA/SF = 50/50; D, PLLA/SF = 30/70; E, pure SF. (d) The biocompatibility of PLLA/SF nanofibers was measured as the OD values using L929 cells and cell counting kit-8. TCP, tissue culture plates. Scale bar = 10 μm. ∗∗.
