Fig. 7From: Ternary MXene-loaded PLCL/collagen nanofibrous scaffolds that promote spontaneous osteogenic differentiationALP activity and mineralized nodule formation of MC3T3-E1 preosteoblasts on PLCL, PLCL/Col, PLCL/MXene, PLCL/Col/MXene nanofibrous matrices. a ALP activity, b digital photographs of von Kossa-stained samples and c their colorimetric quantification. Quantitative analysis was performed using ImageJ software based on digital photographs of b. The mineralized bone nodules are stained with dark-brown color (scale bar = 5 mm). The data are expressed as the mean ± SD (n = 6). Asterisk (* and **) denote a significant difference compared to the control, *p < 0.05, while ‘ns’ denotes not significant. All photographs are representative of six independent experiments with similar resultsBack to article page
