Ischemic and control animals received a series of BrdU injections (50 mg/kg, i.p., twice daily) 9–12 d after surgery.
BrdU immunoreactive nuclei labeled by FITC detected by immunofluorescence microscopy (n = 6 per group).
BrdU-labeled cells also immunoreactive for NeuN or GFAP, as detected by confocal microscopy (see Materials and Methods).
