Abstract

Microparticles are carriers of signals for intracellular signal transduction. These carriers include proteins, mRNAs, microRNAs and other bioactive substances. Platelets are a major source of circulating microparticles, and microparticles are closely associated with the development of certain cardiovascular diseases. In the present study, a method for separating, extracting and identifying platelet‑derived microparticles was developed and differences in the expression of surface proteins on microparticles harvested from platelets stimulated by vortexing or treatment with thrombin was investigated. The counts, composition, sizes and inner structures of microparticles were determined using flow cytometry and transmission electron microscopy. Additionally, it was demonstrated that platelets could be readily activated, and a large quantity of microparticles with varying complex compositions, structures and sizes were derived from activated platelets. High purity platelet‑derived microparticles were obtained by gradient centrifugation. However, the microparticles derived from platelets stimulated by thrombin treatment or vortexing differed significantly in the levels of CD63. The present study aimed to provide improved options for the extraction and identification of microparticles.
