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 4 weeks after surgery

Group	Bone Volume (%)	Bone mineral density (g/mm3)
Control	12.646 ± 2.629	0.070 ± 0.020
Matrigel	21.159 ± 3.154*	0.100 ± 0.032
M + B	24.383 ± 4.630*	0.136 ± 0.038
M + B + V	35.201 ± 3.021**.a	0.231 ± 0.030**
MSC	27.262 ± 3.479**	0.171 ± 0.045*

P<0.05 as compared with the Control group.
P<0.01 as compared with the Control group.
P<0.05 as compared with the M + B 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.
