Biomolecular Signaling Vesicles
The Biochemistry of MSC-Derived Biomolecular Signaling Vesicles
Exosomes are nano-scale extracellular vesicles, 30 to 150 nanometers in diameter, secreted by mesenchymal stem cells as a primary mechanism of intercellular communication. They carry a defined cargo of proteins, microRNA, messenger RNA, and signaling lipids. ExaVeyra supplies cGMP-manufactured biomolecular signaling vesicles for topical aesthetic treatments in clinics and for medical, molecular biology, and biochemistry research.
Biogenesis and Vesicle Architecture
How MSC-Derived Vesicles Are Formed and Characterized
Vesicle biogenesis begins with inward budding of the endosomal membrane to form intraluminal vesicles within multivesicular bodies. Fusion of the multivesicular body with the plasma membrane releases these vesicles into the extracellular space. The pathway is governed by the ESCRT machinery, with key contributions from Tsg101, Alix, and Syntenin-1. Cargo selection occurs during intraluminal vesicle formation and depends on the metabolic state of the parent cell.
Analytical Characterization
HPLC, RNA quantification assay, and NanoSight NTA confirm exosome identity and formulation integrity on every lot documented in the certificate of analysis.
ESCRT and Biogenesis Proteins
Tsg101, Alix, and Syntenin-1 drive cargo sorting and vesicle formation. Their presence on isolated vesicles confirms an endosomal origin consistent with MISEV 2023 characterization guidance.
Heat Shock and Chaperone Cargo
HSP70 and HSP90 are abundant within vesicles and are studied for their role in protein folding, stress response signaling, and target cell uptake mechanisms.
MicroRNA Cargo Profile
Characterized miRNA species include miR-21, the miR-29 family, miR-125b, miR-126, miR-143, miR-145, miR-146a, and the let-7 family. These regulatory RNAs are studied for their roles in gene expression modulation in recipient cells across multiple research contexts.
Membrane Lipid Composition
Phosphatidylserine, sphingomyelin, cholesterol, and ceramides provide structural integrity. The lipid bilayer protects cargo from extracellular degradation and supports membrane fusion with target cells during vesicle uptake.

Frequently Asked Questions
Biomolecular Signaling Vesicle FAQ
What are biomolecular signaling vesicles and how do they differ from whole-cell biologics?
Biomolecular signaling vesicles, also called exosomes, are 30 to 150 nanometer extracellular vesicles secreted by cells. They carry a cargo of proteins, miRNA, mRNA, and lipids, and they communicate at the paracrine level. Unlike whole-cell therapies, vesicles are acellular. They do not replicate and they carry none of the immunogenic risk associated with live cell transplantation. They are supplied for topical aesthetic treatments in clinics and for medical, molecular biology, and biochemistry research.
Why are MSC-derived vesicles studied more often than vesicles from other cell sources?
Mesenchymal stem cells produce vesicles with a characteristic cargo profile rich in growth factors, regulatory miRNA, and signaling proteins. Perinatal sources, including umbilical cord, placental, and Wharton's jelly tissue, are studied because the cells exhibit higher proliferative capacity and a younger epigenetic profile compared to adult tissue sources. ExaVeyra supplies MSC-derived vesicles with full characterization and lot documentation.
