Characterization of PGA/PLA mesh and hADSCs-PGA/PLA complex. Cylinder-shaped PGA/PLA mesh (a). SEM examination of PGA/PLA polymer (scale bars: 200 μm, (b)). Mechanical property of PGA fiber alone and PGA/PLA complex (c). CM-Dil labeled (stained red) hADSCs-PGA/PLA complex 3 days after seeding (scale bars: 200 μm, (d)). SEM examination of hADSCs-PGA/PLA complex with an initial cell seeding density of 10 × 10⁶/mL cultured 14 days after seeding (scale bars: 500 μm, (e)). Live (stained green) and dead staining (stained red) of hADSCs-PGA/PLA complex 21 days after seeding visualized by laser confocal microscopy (scale bars: 100 μm, (f)).
