Effect of matrigel-based HA/PCL scaffold with osteogenic, angiogenic factors and mesenchymal stem cell on bone volume and bone mineral density in a rat segmental defect model at 8 weeks after surgery

Group	Bone Volume (%)	Bone mineral density (g/mm3)
Control	14.918 ± 2.710	0.201 ± 0.115
Matrigel	26.760 ± 1.493	0.264 ± 0.023
M + B	26.529 ± 2.255	0.196 ± 0.013
M + B + V	28.800 ± 6.436*	0.260 ± 0.043
MSC	30.790 ± 5.954*	0.235 ± 0.058

P<0.05 as compared with the Control group.
Values are expressed in mean ± S.D. (n=6).
Control=no graft with 5 mm femoral segmental defect; Matrigel=grafting of matrigel based HA/PCL scaffold; M + B=grafting of matrigel based HA/PCL scaffold with BMP-2; M + B + V=grafting of matrigel based HA/PCL scaffold with BMP-2 and VEGF, MSC=grafting of matrigel based HA/PCL scaffold with BMP-2, VEGF and mesenchymal stem cell.
