Abstract:
The three dimensional (3-D) poly(trimethylenecarbonate-co-epsilon-caprolactone)-block-poly(p-dioxanone) scaffold was made using a wet electrospinning method and its application as a tissue engineered matrix was evaluated for bone regeneration. The scaffold was highly porous (90%) and interconnected among pores. Under scanning electron microscopy, the cells of the center of the scaffold showed healthy well attached shape even at 4 days after seeding. The osteoblastic MC3T3-E1 cells proliferated 1.2 times faster at 4 day, 1.5 times faster at 7 days after seeding as compared with the control in the scaffold (P < 0.05). The activity of alkaline phosphatase, a bone formation marker, of cells seeded in the scaffold was nearly four times faster compared to control 28 days after seeding (P < 0.05). Taken together, newly developed 3-D poly(trimethylenecarbonate-co-epsilon-caprolactone)-block-poly(p-dioxanone) scaffold is a promising candidate for bone regeneration.
