Exosomes

How TFF works, filter formats compared, and why EVlution belongs on your bench

EVlution, a new affordable bench top Tangential Flow Filtration (TFF) system launches today. It makes scalable, reproducible extracellular vesicle purification accessible to more laboratories, accelerating innovation in EV research and translational development.

Embryo implantation is a tightly timed conversation between embryo and endometrium; one that has to coordinate adhesion, immune tolerance, tissue remodelling, and blood-vessel changes within a narrow window of implantation. A major set of words in that conversation are extracellular vesicles (EVs), including exosomes; nano-sized packages released by cells that carry proteins, lipids, and nucleic acids (like miRNAs) to influence recipient cells.

If cytokines and growth factors send clear signals, extracellular vesicles (EVs) are complex chords. They have emerged as a powerful and versatile mode of communication. But how clear can the instructions from these complex particles be?

Since emerging in the last 20 years, expectations for exosomes have developed into hype in some areas. What is their real potential?

There are a wide variety of technologies available to concentrate and purify EVs and exosomes. Choosing the right one for your sample and downstream application is critical.

EVs are best known in the context of mammalian systems, where exosomes and microvesicles play critical roles in intercellular communication. However, plants also release vesicle-like particles with intriguing parallels, and key differences, from their animal counterparts.

Natural killer (NK) cells are part of the innate immune system and can identify and destroy cancer cells without prior sensitization to specific targets. These lymphocytes act as the body's first line of defense, using specialized receptors to distinguish between healthy and abnormal cells.

How robust is the evidence supporting the effectiveness of exosomes in costmetics? Where do these exosomes come from? And how large is the market for exosome-infused products?

Isolating EVs in a form compatible with downstream next-generation sequencing (NGS), particularly for small RNA analysis, can be technically challenging. But using the right kits to process the samples, many different groups have now developed an efficient workflow that is generating valuable EV microRNA data.
