CD36 and essential thrombocythemia: However, ET patients had higher values of CD36+ cells (p < 0.001), PMPs/total number of thrombocytes (p = 0.009), reticulated thrombocytes (p = 0.006) and absolute reticulated thrombocytes (p = 0.09), but a similar total number of PMPs (p = 0.0221), versus subjects exhibiting reactive thrombocytosis.
