Fluorescent staining images of initially attached cells on 2D disks (A) and total number of attached cell on 2D disks (B). The result in (A) qualitatively demonstrated that more viable rat BMSCs were observed in composite disks with higher amount of HA and the result in (B) verified that total attached cell number in PPF/HA 10% and 20% group were significantly higher than in the PPF control groups. Five pictures were obtained from each biological sample and biological quadruplicates were tested. + indicates a significant difference compared to PPF control group (p<0.05).
