Mechanical characteristics of PCL/gelatin composite electrospun scaffolds with and without crater-like structures. (A) Stress–strain curve of PCL/gelatin (100/0, 75/25, and 50/50) scaffolds without crater-like structures and (B) with crater-like structures. (C) Elastic modulus, (D) breaking stress, and (E) breaking strain of the scaffolds with and without crater-like structures. (*p < 0.05 vs. 50/50 PCL/gelatin WO, **p < 0.01 vs. 50/50 PCL/gelatin WO, ×p < 0.05 vs. 50/50 PCL/gelatin WC, ××p < 0.01 vs. 50/50 PCL/gelatin WC, +p < 0.05 vs. 50/50 PCL/gelatin WO, ++p < 0.01 vs. 50/50 PCL/gelatin WO, °p < 0.05 vs. 50/50 PCL/gelatin WC, °°p < 0.01 vs. 50/50 PCL/gelatin WC, ### p <0.001 vs. 50/50 PCL/gelatin WO, −p < 0.001 vs. 50/50 PCL/gelatin WC).
