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

Figure 5

Tissue reactivity to implanted materials at 7 days. (a) this shows mild inflammatory reaction mediated by mononuclear monocytes in response to the implanted CPC-1 (arrows). (b) Implanted CPC-2 at 7 days shows a moderate inflammatory reaction mediated by mononuclear cells. (c) Implanted HA at 7 days exhibits an area of collagen degradation (arrows). (d) Example of the inflammatory reaction characterized by small dilated blood vessels and presence of giant cells observed in response to all the implanted materials (CPC1 shown) H&E X200.
