Figure Lengend Snippet: ( A ) Representative immunoblots and quantitative analysis of the calpain- (145/150 kDa) and caspase-specific fodrin cleaved products (120 kDa) in sham-operated mice, and mice treated with vehicle, tPA, tPA in combination with rADAMTS 13, and rADAMTS 13 24 hours after MCA occlusion. The gels have been run under the same experimental conditions. ( B ) Six fields selected for immunohistochemical quantification of LC3, TUNEL, and FJB-labeled cells in the peri-infarct area in Nissl-stained coronal sections in all the groups. ( C ) Representative photomicrographs of TUNEL staining and quantification of TUNEL-positive cells in the ischemic brain of mice treated with vehicle, tPA, rADAMTS 13 in combination with tPA, and rADAMTS 13 24 hours after MCA occlusion. ( D ) Representative photomicrographs of Fluoro-Jade B (FJB) staining and quantification of FJB-positive cells in the ischemic brain of mice treated with vehicle, tPA, rADAMTS 13 in combination with tPA, and rADAMTS 13 24 hours after MCA occlusion. ( E ) Representative immunoblots of LC3 and quantification of the LC3-II/LC3-I ratio in sham-operated mice, and mice treated with vehicle, tPA, tPA in combination with rADAMTS 13, and rADAMTS 13 24 hours after MCA occlusion. The gels have been run under the same experimental conditions. ( F ) Representative photomicrographs of LC3 staining and quantification of LC3-positive cells in the ischemic brain of mice treated with vehicle, tPA, rADAMTS 13 in combination with tPA, and rADAMTS 13 24 hours after MCA occlusion. Bar = 30 μm. Values are mean ± SD (n = 5 per group). *P < 0.05.
