Embolization studies after cremaster arteriole and venule injuries. Embolization studies downstream of arteriole and venule injuries. All transgenics are on a F8^null background. Open bars indicate arteriole studies and closed bars indicate venule studies. N = 18 videos per arm. Mean ± 1 SD shown. *P < .035 relative to WT. **P < .04 relative to phF8.38. (A) Number of detectable emboli. (B) Average relative embolic size determined by mean fluorescence. (C) Total embolic mass per study determined from the number and size of emboli.
