r-hu ADAMTS13 reduces infarct volume after focal cerebral ischemia in WT mice. Representative TTC staining of coronal brain sections of 1 mouse for each treatment and infarct volumes 22 hours after focal cerebral ischemia in mice treated with (A) vehicle or r-hu ADAMTS13 (derived from HEK293 cells) and (B) vehicle or r-hu ADAMTS13 (derived from CHO cells) are shown.
