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.
