Abstract:
Platelets play a major role in hemostasis, but are also involved in vascular biology processes such as angiogenesis and tumor metastasis. Activated platelets release many proteins favoring wound healing and promoting angiogenesis. Microparticles (MP) are small plasma membrane vesicles shed from cells upon their activation or apoptosis. Platelet-derived microparticles (PMP) constitute the majority of the pool of MP circulating in the blood. PMP express and may transfer functional receptors, stimulate the release of cytokines, activate intracellular signaling pathways, promote angiogenesis, and are involved in tissue regeneration and cancer metastasis. We investigated the effect of PMP on cancer cells metastasis and their potential beneficial effect in an ischemic stroke model.
Insights

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...
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 platelets, with...
