Cytotoxicity test
The cytotoxicity of scaffolds prepared from PLLA and PCLA using gelatin
nano-non-wovens was examined against Jurkat cells. Due to poor
morphology, no tests have been performed for PCL scaffolds. Since PVP
and Pluronic® are biocompatible substances, their toxic impact was not
examined. Material may be considered non-toxic if, during the entire
period of the culture, the number of living cells that are in contact
with such a material exceeds 50% of the initial state. The number of
viable cells has remained over 95%. It means that these scaffolds are
non-toxic to the examined cells (Fig. 10). Similar results for the
scaffolds prepared from PCLA were slightly worse (but also non-toxic); a
decrease in the viability of the cells (down to ca.70%) was observed on
the 8th day.
