Abstract

Official abstract text for this publication.

A fluidic system for producing extracellular vesicles from producer cells, including at least one container, a liquid medium contained by the container and producer cells, characterised in that it also includes microcarriers suspended in the liquid medium, the majority of producer cells being adherent to the surface of the microcarriers, and a liquid medium agitator, the agitator and the dimensions of the container being adapted to control a turbulent flow of the liquid medium in the container.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for ex vivo production of extracellular vesicles from producer cells, comprising: controlling an agitator causing a turbulent flow of a liquid medium in a container, the liquid medium being agitated for more than thirty minutes, the container comprising an output, the liquid medium comprising producer cells adhering on the surface of the microcarriers, the microcarriers being suspended in the liquid medium; and collecting the liquid medium comprising extracellular vesicles at the output of the container, wherein the agitator is controlled to cause the turbulent flow of the liquid medium to form vortices so that the turbulent flow has a Kolmogorov length of more than or equal to 33 μm and less than or equal to 75 μm, and wherein said turbulent flow method allows the production of the extracellular vesicles with a higher yield as compared to a serum starvation method for producing extracellular vesicles. 2. The method according to claim 1 , wherein a separator depletes part of the liquid medium collected at the output of the container of extracellular vesicle, and wherein the part of the liquid medium is reintroduced into the container.
