(a) Thickness of the macrophage-rich region around the implant on day 7. The control group was the hydrogel without cells. (b) Representative images showing macrophage infiltrations in the peri-implant region for each treatment group; arrows (↔) illustrate the thickness of the macrophage-rich region (brown, CD68 staining, scale bar 500 μm), and arrows (⇔) illustrate the total immune cell infiltrations in the peri-implant region.
