Platelet activation. (A and B) Addition of myocardial matrix to human platelet-richplasma was done at a standard concentration (1:10,000) (A) and a high concentration (1:2500) (B) and the samples were evaluated for at least five minutes. After the samples plateaued, agonists were added (at 10 minutes). (C) A control was performed after four hours to ensure normal activity of the samples and validity of the data in response to agonists. Data shown are representative traces from 4 repeated experiments.
