Figure 6.

Lectin immunohistochemical staining, 10× (a) and 20× magnification (b), representative images (not all groups are depicted). Brown cells = lectin-positive; blue cells = lectin-negative (counterstained with hemalaun). (a) After 1 week, lectin-positive cells were diffusely dispersed in the connective tissue between beads. A fraction of the infiltrating cells stained clearly positive for lectin (arrow). (b) After 4 weeks, the connective tissue between the microbeads was highly vascularized (arrows). No differences were evident between groups with nBG and without nBG in qualitative microscopic evaluation.
