In vivo BV/TV results estimated with μCT and histomorphometry are presented as scatter plots. Individual data points are depicted with dots and middle bar represents the mean. Top and bottom bar represents standard deviations. The top two scatter plots (a and d) represent the paired sub-study with an empty defect and a HT-PCL scaffold. Middle two scatter plots (b and e) illustrate the PCL vs. HT-PCL sub-study, whereas bottom scatter plots (c and f) represent autologous BMSCs on HT-PCL scaffolds vs. autologous DPSCs on HT-PCL scaffolds.
