Fig. 4From: Ternary MXene-loaded PLCL/collagen nanofibrous scaffolds that promote spontaneous osteogenic differentiationCytotoxicity profiles of MXene NPs against MC3T3-E1 preosteoblasts. a CCK-8 assay and b LDH assay on MC3T3-E1 preosteoblasts treated with different concentrations of MXene NPs. c Morphological changes of MXene NPs-treated cells observed by optical microscopy. The data are expressed as the mean ± SD (n = 6). An asterisk (*) denotes a significant difference compared to the non-treated control, p < 0.05. All micrographs are representative of six independent experiments with similar resultsBack to article page
