Figure 3: Tracking of CFSE-labelled CD34 + and CD34 - HUCB cells in serial sections of SH in rat brains 29 days after MCAO. A: control animal without cell therapy, HE staining; B: control animal, UV microscopy with green fluorescence; C: HUCB mononuclear cell treatment, green fluorescence, the borderline between the necrotic central area and the border zone to unaffected tissue is marked according to HE serial section; D: HUCB mononuclear cell treatment, red fluorescence; E: CD34 + HUCB cell treatment, HE staining; F: CD34 + HUCB cell treatment, green fluorescence (inverse colours); G: CD34 - HUCB cell treatment, phase contrast microscopy; H: CD34 - HUCB cell treatment, green fluorescence. 400fold magnification in all images.
