Fig. 8.

Representative pseudo-colour images of the surface of polished β-TCP cylinders from white light interferometry measurements. Image (a) shows batch CaP5, with a Ca/P of 1.500 after 24 h of contact with cell culture medium with no cells (NC) and image (b) after 24 h with macrophages (MA); images (c), (d), (e) and (f) represent batches CaP1 (Ca/P = 1.496), CaP3 (Ca/P = 1.497), CaP5 (Ca/P = 1.500) and CaP6 (Ca/P = 1.502) after 24 h of contact with osteoclasts (OC). Green colour represents the reference plane and blueish colours the zones below this reference. In the case of images (c), (d), (e) and (f), blueish colours show the areas resorbed by the osteoclasts (white arrows). Black arrows indicate lines from mechanical polishing.
