Live/Dead assay of loaded stem cells. (A) The assay showed a greater amount of cells inside the MC-PCL-HA scaffolds, compared to BMSC-seeded scaffolds, during the first 2 weeks of culture, with more red-stained dead cell observed in MC-PCL-HA scaffolds. (B) The ratio of live/dead cells in Group A decreased at 1 week and increased at 2 weeks in vitro culture, and this ratio in Group A was lower than that of Group B. *p<0.05.
