In healthy people, exosomes – tiny structures secreted by cells to allow intercellular communication – prevent clumping of the protein that leads to type 2 diabetes. Exosomes in patients with the disease don’t have the same ability. This discovery by ...

Exosomes are released by most cells and can be isolated from all biofluids including urine. Exosomes are small vesicles formed as part of the endosomal pathway that contain cellular material surrounded by a lipid bilayer that can be traced to ...

Vesicular-mediated communication between cells appears critical in many biological processes. Extracellular vesicles (EVs) released from healthy and diseased cells are involved in a network of exchange of biologically active molecules. Since EVs present in biological fluids carry the signature of ...

Cell-to-cell communication, or signaling, is absolutely essential in orchestrating the activities of cells in multicellular organisms, to grow, develop, detect environmental changes and compensate for them in an internal, coordinated fashion. In the last few years, a considerable amount of ...

In the last decades, several studies demonstrated that the tumor microenvironment is a critical determinant not only of tumor progression and metastasis, but also of resistance to therapy. Exosomes are small membrane vesicles of endocytic origin, which contain mRNAs, DNA ...

The interest in extracellular vesicles (EVs) has grown exponentially over the last decade. Evolving evidence is demonstrating that these EVs are playing an important role in health and disease. They are involved in intercellular communication and have been shown to ...
Read More »Magnetic bead-based isolation of exosomes
Exosomes are here defined as extracellular vesicles (EVs) in the approximate size range of 30-100 nm in diameter, and are observed in most body fluids containing typical exosomal markers such as CD9, CD63, and CD81. Potential subpopulations of exosomes can ...

In recent years, there has been an exponential increase in the number of studies aiming to understand the biology of exosomes, as well as other extracellular vesicles. However, classification of membrane vesicles and the appropriate protocols for their isolation are ...
