ADAMTS13 deficiency-mediated enhanced neutrophil recruitment is VWF dependent. (A) Representative photomicrographs stained for neutrophils (Ly6B.2-positive cells are stained brown and indicated by the black arrows) and counterstained with hematoxylin from one mouse of each genotype. Scale bar indicates 50 μm. (B) Quantification of immunoreactive cells in the infarcted and surrounding region. Each dot is a mean of 16 fields from 4 serial sections (separated by 30 μm) per mouse. Horizontal bars indicate mean values. NS indicates nonsignificant.
