Figure 14.7 X-ray photograph of rat femur defects treated with scaffolds or
scaffold/MSC constructs at 3 days, 3 weeks, and 6 weeks post surgery. BG-COL-PS/
MSC-treated femurs exhibited the highest degree of healing from week 3 to week 6.

abitilty of HA [3]. Xu et al. studied the fate of rat mesenchymal stem cells
(rMSCs) seeded on bioglass-collagen-phosphatidylserine (BG-COL-PS)
or bioglass-collagen (BG-COL) scaffolds and cultured for 21 days in vitro .
Their results indicated a higher degree of attachment and osteogenic
