Histologic sections of defects filled with s-HAp 2 weeks after implantation. (a) Most surfaces of HAp granules are surrounded by connective tissue. (b) A multinucleated cell (MNC) is observed around the s-HAp granules. This MNC is characterized by a uniform cytosolic stain with a smaller number of endosomal structures.
