Fig 12. Cell growth after 3 days of fibroblast culture on TCP, PLA film, and a suit obtained with gelatin nano-non-woven.
After 24 h of culture, there were far fewer cells (2200 ± 800) on the surface of the PLA film than in the control TCP (3500 ± 400) culture. It was similar in scaffolds obtained with wet phase inversion using gelatin nanofibers, were on the lower surface there were fewer cells (1300 ± 1500) than on the upper (3400 ± 1100), this result was burdened with a large error. After 48 h of culture, the cell number increased several times. In scaffoldings obtained with the addition of gelatin nanofibers, 3400 ± 1700 cells were observed on the lower surface and 5500 ± 1600 cells on the upper surface. After 72 h, the number of cells increased again. In scaffolds obtained using gelatin nanofibers, a larger number of cells were observed on the upper surface (9800 ± 3000) than on the lower surface (9800 ± 3000).
