Abstract:
Platelet-derived microparticles (PMPs) represent the most abundant microparticle (MP) subtype. Their presence reflects platelet activity, physiopathology, and the thrombotic state of cancer patients. The quantity and composition of PMPs strictly depends on the way MPs were generated. Because platelets play a key role in cancer progression, as well as formation of metastasis, PMPs also may be important in the proliferation of cancer cells, cancer cell interactions, metastatic progression, angiogenesis, and inflammation. Alternatively, the concentration of circulating PMPs may differ according to the stage of a cancer and thus potentially could be used as a biomarker. Here we review the mechanisms underlying the generation and composition of PMPs and the clinical and experimental studies describing the involvement of PMPs in cancer and the Trousseau syndrome. Lastly, we focus on their clinical relevance, as well as their potential application as biomarkers in cancer.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
