Microvesicle
Type of extracellular vesicle

Microvesicles are a type of extracellular vesicle (EV) that are released from the cell membrane. In multicellular organisms, microvesicles and other EVs are found both in tissues and in many types of body fluids. Delimited by a phospholipid bilayer, microvesicles can be as small as the smallest EVs or as large as 1000 nm. They are considered to be larger, on average, than intracellularly-generated EVs known as exosomes. Microvesicles play a role in intercellular communication and can transport molecules such as mRNA, miRNA, and proteins between cells.
Begin with the source’s own compact description: “Microvesicle” is type of extracellular vesicle. The dossier treats that line as a proposition to test through Microvesicle, Type and extracellular, not as a finished interpretation.
Why this record matters
The phrase “type of extracellular vesicle” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 14, 2026. The first chronological checks are 1000.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
