Growth kinetics of A-W scaffold seeded PA-MSC and CD271-MSC. a Graph showing the concentration of DNA obtained from MSC seeded scaffolds cultured in MSC expansion medium for 1, 3, 7 and 14 days. Day 0 value was obtained from unseeded cells. Error bars represent the SEM of 5 independent experiments. *** p ≤ 0.001 (two way paired ANOVA with Bonferroni post-test). b-e Scanning electron microscopy images showing MSC seeded scaffolds after 14 days of culture in MSC expansion medium. Scale bars represent 2 mm (b, d) and 500 μm (c, e). Images are representative of 3 independent experiments
