Mechanical properties of different electrospun scaffolds and cell-seeded scaffolds. (A) Tensile modulus (p = 0.0038 among experimental groups, Kruskal–Wallis test; **p < 0.01 between groups, Mann–Whitney test), and (B) UTS (p = 0.0003 among experimental groups, Kruskal–Wallis test; ***p < 0.001 and ****p < 0.0001 between groups, Mann–Whitney test) for dry PLA, collagen, and coaxial scaffolds. (C) Tensile modulus (p = 0.0004 for interaction, p < 0.0001 for the existence of cells, and p < 0.0001 among experimental groups, two-way ANOVA) and (D) UTS (p = 0.0076 for interaction, p = 0.0008 for the existence of cells, and p < 0.0001 among experimental groups, two-way ANOVA; Bar+ *p < 0.05, Bar+ ***p < 0.001, and Bar+ ****p < 0.0001 between groups, Mann–Whitney test; ##p < 0.01, and ###p < 0.001 acellular versus cellular scaffolds in the same type of scaffolds, Mann–Whitney test) of electrospun PLA, collagen, and coaxial scaffolds in culture with or without cells for 2 weeks. ANOVA, analysis of variance; UTS, ultimate tensile strength.
