Leptomeningeal findings following MCAO. An active chronic fibrosis was observed (a and b) in all groups subjected to middle cerebral artery occlusion with or without BM MNC (c to f, HE staining). Only a slight increase of connective tissue proliferation was observed in sham-treated subjects (c). Infiltration with lymphocytes was observed in all groups (i to m, HE staining, white arrows). Lymphocytic infiltration was lowest in BM MNC-treated subjects (g, h) in both hemispheres and compared to partial and total MCAO. Please note augmentation of fibroblasts (k to m, black arrows) in all groups subjected to MCAO. Graphs: white line in box plots indicates the median, whiskers give the 95% confidence interval. */#p < 0.05 versus total MCAO/partial MCAO. Scale bar in (f) represents 100 μm in (c) to (f) and scale bar in (m) indicates 25 μm in (i) to (m), respectively
