Title: Automated production and collection
IPC: C12N1/00
Filed: 2021-11-26
Abstract: PROBLEM TO BE SOLVED: To provide production methods, isolation and/or collection methods of cellular products released or secreted from cells. 
     SOLUTION: Cells are expanded in the intracapillary (or extracapillary) space of a bioreactor of a cell expansion system with media. The cells release cellular products into the fluid space of the bioreactor. Examples of such released cellular products include extracellular particles, such as extracellular vesicles (EVs). To collect the extracellular particles released from the cells being expanded instead of extracellular particles from other sources, a washout step is used to eliminate serum proteins prior to collecting the released extracellular particles from the expanding cells. The released cellular products are collected or concentrated through the control of outlet parameters, while nutrients reach the cells through diffusion of media through a semi-permeable membrane. The released cellular products are then harvested.
