Transmission electron microcopy, 6 weeks after operation. (A–C) Multinucleated macrophages (mM) are located at the surface of gas voids (gb), contain resorbed implant material (arrow), and hold processes (p). (D–F) Gas voids are also covered by fibroblast-like cells (f) and uninucleated macrophages (m). Imp: implant.
