Overall, similar macrophage activities were observed around BAG and �-TCP granules. However, temporarily increased foreign body giant cell (FBGCs) accumulation was observed after implantation of hASC seeded �-TCP granules as compared to BAG granules at week 4. G1 � G4 = groups 1 - 4; arrows with asterisks indicates statistical differences between BAG and �-TCP.
