hematopoietic system
thrombocytopenia ( J:134343 )
• mice have significantly lower number of platelets in circulation (770 x 109/L) than in littermate controls (1020 x 109/L)

homeostasis/metabolism
decreased susceptibility to induced thrombosis ( J:134343 )
• mice have a delayed occlusion time of 99 minutes after photochemical injury of the common carotid artery compared to 57 minutes for wild-type controls
• large, irregular spikes in carotid artery blood flow are observed after injury compared to the linear drop in flow that occurs in wild-type controls
increased bleeding time ( J:134343 )
• mean bleeding time from the tail vein (150 seconds) is almost twice that of their littermate controls (81 seconds)
