Polymeric-Calcium Phosphate Cement Composites-Material Properties: In Vitro and In Vivo Investigations

Figure 6

Tissue reactivity to implanted materials at 30 days. (a) Note the thick fibrous capsule (arrows) and the small dilated blood vessels in response to the implanted material (CPC-1) (arrows). (b) CPC-2 at 30 days demonstrates a thin fibrous capsule (arrows) and few macrophages adjacent to the implanted material. (c) Area showing a moderate inflammatory reaction and a thin fibrous capsule as seen in CPC-2 and HA implanted materials (CPC-2 shown). H&E X200.
