FIG. 5.

Radiographical analysis of BMP2-induced bone formation through delivery of AdBMP2-transduced cells either encapsulated in PEGDA hydrogel microspheres (+) or directly injected (−) in wild-type mice that have been previously exposed to AdEmpty-transduced cells. (A) Bone volume was quantified and sample (n = 3) averages and SEM depicted in the graph. (B) Bone density was quantified and sample (n = 3) averages and SEM depicted in the graph. *** indicates statistically significant difference (p ≤ 0.00005).
