The cell number and viability (XTT assay) 24 h after cell seeding, and on days 7, 14 and 21 of culture. The results of the XTT assay are presented as the absorbance level. It was determined as a linear relationship between cell number and viability. Seven independent experiments were performed. The data are presented as means ± standard deviation. Cell number is in black; cell viability is in grey. Student’s t-test was used for statistical analyses. *p < 0.05 (considered significant)
