Aspirin responsive platelet thrombophilia in essential thrombocythemia and polycythemia vera

Figure 4 Baseline P-selectin levels (A), and arachidonic acid-induced P-selectin levels (C) in JAK2V617F mutated essential thrombocythemia and JAK2 wild type essential thrombocythemia; monocyte CD11b (B), and LPS-induced monocyte tissue factor expressions (D) in controls, essential thrombocythemia without thrombosis and essential thrombocythemia with thrombosis. Majority of essential thrombocythemia (ET) patients were on myelosuppressive therapy (mainly hydroxyurea), and a minority used aspirin at time of laboratory investigations. AA: Arachidonic acid.
