Representative microphotographs of the of the induced membrane formed at the interface with the PMMA spacer 3 weeks after IMT surgery. (A, B) 2 representative animals of the group 2.1 (n = 4, non-infected – membrane evaluation). A higher magnification of the marked insets in images A and B are given on the right side of the images (a_i, a_ii and b_i, b_ii). PMMA-embedded, GE-stained, thick-sections, scale bar 2 mm (A, B); or 200 μm (a_i, a_ii), 100 μm (b_ii) and 50 μm (a_ii). White arrows mark fibrous tissue (a_i, b_i), black arrows indicate early state granulomatous inflammation (a_ii, b_ii)
