Name | Implant composition | Initial activity (µCi) | BMP-2/implant (µg) |
---|---|---|---|
Gelatin | Gelatin hydrogel | 6.0 ± 0.5 | 9.8 ± 0.8 |
Mps/Gelatin | Mps in a gelatin hydrogel | 3.7 ± 0.6* | 6.0 ± 1.0* |
Mps/PPF | Mps in a solid PPF cylinder | 5.6 ± 0.5 | 9.1 ± 0.8 |
Mps/PPF/Gelatin | Mps in a PPF cylinder surrounded by a gelatin hydrogel | 5.8 ± 0.4 | 9.5 ± 0.6 |
Mps = poly(lactic-co-glycolic acid) microparticles loaded with BMP-2
significantly lower loading relative to other implants.
