(Left) Representative SEM micrographs of MEW PCL mesh show the well-aligned (0–90°-oriented junctions) fibrous 3D architecture with 500 µm pore size and a mean fiber diameter of 3.16 μm. (Middle) SEM micrographs of hMSCs-MEW PCL mesh interaction after 3 days of culture. Note significant cell attachment, proliferation, and protrusion along and around the printed PCL fibers. Filopodia are also indicated (white arrows). (Right) Fluorescence staining of hMSCs-MEW PCL mesh interaction after 3 days showing phalloidin (Red) staining of filamentous actin and DAPI (Blue) for the nucleus.
