Effects of beta2-glycoprotein-I on platelet aggregation in cord versus adult whole blood.

abstract：:The ADP receptor P2Y12, the thromboxane A2 receptor (TXA2R) and the C-type lectin-like receptor 2 (CLEC-2) mediate platelet activation by different mechanisms. Only little is known about the expression of the receptors in human megakaryopoiesis. Our study aimed to establish a flow cytometry (FC) method for the measure...
