Fig 9. Variation in health of olfactory ensheathing cells when cultivated (DMEM media, 5 days, 37°C, 5% CO2) on solvent cast films fabricated from commercial chitosan samples with different DDAs, as measured by: (a) mitochondrial activity, expressed as % of cells in asynchronous growth (100%), and membrane integrity expressed as % of lysed cells (100%); (* Significant difference, P < 0.05, n ≥ 3).
