FIG. 3.

High-magnification trichrome sections show that in untreated rats, cells (mainly erythrocytes and some inflammatory cells, white arrows) infiltrated module-derived channels at day 3 (a). There was only moderate infiltration at day 7 (b) and less infiltration at day 14 (c). In clodronate liposome–treated rats, there was little cellular infiltration at day 3 (d), more at day 7 (e), and minimal infiltration at day 14 (f). Scale bar = 25 μm.
