Fig 13. Evaluation of the fibroblast growth morphology on stable PLA (a), on the lower (b), and upper (a) scaffolds of PLA obtaining with gelatin nano-non-woven. Sample cells are marked with red circles. 50 µm
Cell growth morphology was assessed (Fig 13). Cells growing on stable PLA had the wrong morphology. They were rare, shrunken - rolled into balls (Fig 13.a). On both sides of the suit made using gelatin nanofibers, the cells had the correct morphology - they were uncracked and flattened. On the lower surface (less porous, Fig 13.b) the cells grew in the form of a solid layer tightly covering the surface of the suit. On the upper side (Fig. 13.c), they grew in rhomboid colonies and at specified intervals between them. The above observations show that fibroblasts prefer surfaces with smaller pores for growth.
