FIG. 6.
Evaluation of hemodynamic state (rCBF maps) with perfusion-weighted images (PWI). BMSCs or PMSCs were intravenously injected immediately after the initial MRI scanning (6 h after MCAO). Images obtained 6 h, and 1, 3, and 7 days after MCAO in medium-injected (A), BMSC-treated (B), and PMSC-treated group (C). Summary of rCBF evaluated with PWI in each group: ROI-1 (D), ROI-2 (E), ROI-3 (F), and ROI-4 (G). rCBF ratio (ischemic lesion/contralateral lesion) at 6 h, and 1, 3, and 7 days after MCAO is summarized in D–G. Scale bar = 3 mm. *p < 0.05.
