Tubule formation quantification in samples with endothelial basal medium (EBM). Intersection points, number of tubes, total tube length, and average tube length were quantified. The composite scaffold further enhanced tubule formation compared to control in later time-points. Data are expressed as mean. *p < 0.05, **p < 0.01, and ***p < 0.001 after two-way Anova with Bonferroni post-test analysis compared exclusively with EBM + 2% FBS at each time-point.
