hMSC infiltration on PCL/gelatin composite electrospun scaffolds with and without crater-like structures after 1 day and 7 days of cell seeding imaged by H&E staining. (A) hMSCs on 100/0 PCL/gelatin scaffold without crater-like structures after 1 day and (B) after 7 days. (C) hMSCs on 100/0 PCL/gelatin scaffold with crater-like structures after 1 day and (D) after 7 days. (E) hMSCs on 75/25 PCL/gelatin scaffold without crater-like structures after 1 day and (F) after 7 days. (G) hMSCs on 75/25 PCL/gelatin scaffold with crater-like structures after 1 day and (H) after 7 days. (I) hMSCs on 50/50 PCL/gelatin scaffold without crater-like structures after 1 day and (J) after 7 days. (K) hMSCs on 50/50 PCL/gelatin scaffold with crater-like structures after 1 day and (L) after 7 days (Scale bar = 100 µm). (M) The depth of hMSC infiltration. (WO: the scaffolds without crater-like structures, WC: the scaffolds with crater-like structures), (***p < 0.001 vs. 100/0 PCL/gelatin WO at 1 day, ##p < 0.01 vs. 75/25 PCL/gelatin WO at 1 day, ++p < 0.01 vs. 50/50 PCL/gelatin WO at 1 day, ×××p < 0.001 vs. 100/0 PCL/gelatin WO at 7 day, ###p < 0.001 vs. 75/25 PCL/ gelatin WO at 7 day, and +++p < 0.001 vs. 50/50 PCL/gelatin WO at 7 day).
