Summary
Mesenchymal stem/stromal cell-derived extracellular vesicles (MSC-EVs) show therapeutic potential. Functional proteins within MSC-EVs are key mediators of their immunomodulatory and regenerative effects, offering a cell-free treatment alternative.
Area of Science:
- Cell Biology
- Biochemistry
- Immunology
Background:
- Extracellular vesicles (EVs) are crucial for intercellular communication, carrying diverse biomolecules.
- Mesenchymal stem/stromal cells (MSCs) exert therapeutic effects largely through paracrine factors, including MSC-derived EVs (MSC-EVs).
- MSC-EVs are emerging as a promising cell-free therapeutic strategy.
Purpose of the Study:
- To review the functional proteins within MSC-EVs.
- To elucidate the role of these proteins in MSC-EV-mediated therapeutic effects.
- To compare the proteomic profiles of MSC-EVs and their parental MSCs.
Main Methods:
- Literature review focusing on proteomics and functional analysis of MSC-EVs.
- Analysis of protein cargo within EVs.
- Examination of studies investigating MSC-EVs in disease models.
Main Results:
- EVs contain a complex cargo including proteins, microRNAs, and mRNAs.
- Proteomic analysis reveals distinct protein compositions in MSC-EVs compared to MSCs.
- Functional proteins in MSC-EVs are essential for their immunomodulatory and regenerative activities.
Conclusions:
- Functional proteins are critical components driving the therapeutic capacity of MSC-EVs.
- MSC-EVs represent a viable cell-free therapeutic approach.
- Further research into MSC-EV protein cargo can optimize therapeutic applications.

01:36Overview of Exosomes
3.4K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

01:33Overview of Secretory Vesicles
9.3K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.

5.4K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

4.6K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

16.7K
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of...

01:45Vesicular Tubular Clusters
3.0K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
