Cell metabolic activity and viability. Metabolic activity of viable MSCs was detected by MTT assay on day 1, 7, and 14 (mean ± standard deviation). Results of MTT assay for PCL/PVA, PCL/PVA200HA, PCL/PVA400HA, and PCL/PVA800HA samples (a). Cell viability calculated as derivation of absorbance values from MTT assay to cell counts determined by PicoGreen assay (b).
