Biocompatibility observations of PDL cells cultured on untreated PLGA and PLGAH001FN samples. (A,B) SEM micrographs of PDL-like fibroblasts cultured on (A) untreated PLGA [scale bar (i) 100 μm and (ii) 30 μm] and (B) PLGAH001FN [scale bar (i) 100 μm and (ii) 30 μm] up to 7 days. (C,D) Confocal images of PDL cells cultured on (C) untreated PLGA surface and (D) PLGAH001FN surfaces up to 24 h; (i) and (ii) correspond to superior and inferior surfaces of samples, respectively. Scale bar (C,D) 100 μm. (E) Quantitative resazurin results of PDL cells cultured on PLGA and PLGAH001FN samples up to 24 h. Data are expressed as mean±SD (n=3). PDL, periodontal ligament.
