Exosome and Extracellular Vesicle Production Scale-Up

Continuous production process for Exosomes, Extracellular Vesicles, Microvesicles

Avoid tiresome processing of big volumes of supernatant using a FiberCell Hollow Fibre Bioreactor. Large amounts of EVs can be obtained from practically any type of cell, including mesenchymal stems cells, when cultured continuously at high density in this system. Productivity increases of 40X compared to flask culture have been reported. In addition, the 3D culture environment inside a hollow fibre bioreactor has been shown to be more representative of in vivo conditions compared to flask culture […more]. A medium size 20ml hollow fibre cartridge (C2011) will support continuous post-confluent growth of 1E+9 cells. Examples and publications below…

  • Increase exosome yield by up to 100-fold compared to flask culture
  • Obtain very concentrated exosomes/EVs in small volumes of supernatant
  • High cell density bioreactor culture offers more physiological 3D growth conditions

mesenchymal stem cells production of exosomes in time-scalable process

Simple routine exosome collection process

A FiberCell Hollow Fibre Bioreactor provides a continuous production process enabling periodic harvesting of concentrated EVs in 20ml syringe volumes. No passaging is required. Batch production in multiple flasks is avoided. Click on the article below to learn more.

FiberCell® HFBR easily outperforms T-225 flasks

Flasks were split 1:5 in DMEM/10% FBS until a total of 130 T225 flasks were obtained. DMEM/10% FBS was replaced with DMEM alone and exosomes collected after 2 days.

5X10^8 adipose-derived mesenchymal stem cells were seeded into the hollow fibre bioreactor (C2011 cartridge) and harvests initiated after one week of culture. Medium used in the hollow fibre bioreactors was DMEM/10% FBS in the circulating medium, DMEM without serum in the extra-capillary space.

Total exosomes collected from two HFBR under these conditions equalled that from 3600x T225 flasks in a total volume of 360 mL.
