Ultrastructural immunolocalization of thrombomodulin in human placenta with microwave fixation.

Abstract
Ultrastructural immunolocalization of human thrombomodulin was visualized for the first time in the human placenta; i.e. plasma membrane of microvilli of syncytiotrophoblast was continuously positive with occasional reactivity along the membrane of intracytoplasmic vacuoles. This is consistent with its physiological property as a receptor to thrombin.
