title: Ultrastructural studies of platelets of von Willebrand and normal swine.
abstract: Platelets from normal pigs and pigs with von Willebrand's disease were studied by ultrastructural and scanning electron microscopy. The majority of resting platelets were discoid or abortive-dendritic in gross morphology with an average size of 2.6 micrometer. The number of alpha-granules per platelet section was varied; however, a highly significant positive association was found between platelet size and the number of alpha-granules. These studies characterize porcine platelets more definitively and clearly establish the similarities between platelets from normal and those from von Willebrand pigs.
