The results of cell proliferation with and without stimulation on control and experimental scaffold specimens are shown in Fig. 10. At 1-day and 3-day culture, there is significant difference between with and without compressive stimulation. Additionally, the experimental group showed 1.46 times higher cell proliferation than control group at day-1 with compressive stimulation, and the experimental group showed 2.09 times higher cell proliferation than control group at 1-day without compressive stimulation. In case of 3-day culture, the experimental group showed 1.32 times higher than control group with no compressive stimulation. However, when applying a compressive stimulation, there was no significant difference between experimental group and control group at 3-day culture. At 5-day culture, there is no significant difference between all groups.Fig. 10MG-63 cell proliferation rate on PLGA scaffolds at 1, 3 and 5 day culture with static stimulation (n = 4, *p < 0.05, **p < 0.01)
