Tumor-Educated Platelets Facilitate Thrombus Formation Through Migration

Platelets are small anucleate cells that circulate in the blood and form thrombi. Tumor-educated platelets are the platelets derived from cancer patients. Although many have reported that tumor-educated platelets are associated with cancer-associated thrombosis, their function in this process is poorly understood. Here we first collect the clinical data from 100 different cancer patients, showing that cancer patients are in a hypercoagulable state. Our experiment shows that tumor-educated platelets from melanoma-burdened mouse models can migrate faster and longer, forming more clots (thrombus). However, the plasma from tumor mice can inhibit platelet migration. The RNA sequence profile of tumor-educated platelets shows that many genes associated with cell migration and cell skeleton expressed significantly higher. Our research offers a new insight into the tumor-educated platelets to better understand the thrombus formation.

Automated summary

Platelets are small anucleate cells that circulate in the blood and form thrombi. Tumor-educated platelets derived from cancer patients play a role in cancer-associated thrombosis. Studies show that tumor-educated platelets from melanoma-burdened mouse models demonstrate enhanced migration and clot formation, but are inhibited by plasma from tumor mice. RNA sequence profile of tumor-educated platelets reveals upregulation of genes associated with cell migration and cytoskeleton, shedding light on the process of thrombus formation.
