Characterization of polycaprolactone/hydroxyapatite (PCL/HA) scaffolds before and after cell seeding. A Gross morphology of PCL/HA scaffolds. B Scanning electron microscope (SEM) images showing the macroporous structure of PCL/HA scaffolds at different magnifications (500, 200, 100, 50 μm). The top row shows scaffolds before cell seeding, while the bottom one shows them after cell seeding. C Confocal microscope pictures showing cell morphology and distribution. F-action was marked in red and nuclei were marked in blue. D–F Porosity (D), compression strength (E), and modulus of elasticity (F) of the PCL/HA scaffolds
