FIG. 9.

ED2-stained sections of endothelialized modules show high macrophage infiltration in untreated rats at days 3, 7, and 14 (a–c). For clodronate liposome–treated rats, macrophages were minimal at day 3 (d), but began to repopulate at day 7 (e), and tissue is fully repopulated by day 14 (f). Repopulation by day 7 is also seen in treated collagen-only implants (g, h). A few ED2-positive cells were seen in sham-operated, untreated animals (i) at day 3, reflecting the effect of omental surgery. Scale bar = 100 μm.
