DNA synthesis determined by BrdU incorporation (brown nuclear staining) in the infarcts of (A) MRL/MpJ and (B) C57BL/6 at 4 days do not co-localize with sarcometic actin immunostaining (red). Arrows indicate BrdU positive nuclei (bar = 50 μm). (C) Total BrdU incorporation rates between 1 and 14 days is equivalent in both strains.
