Austrianova and Cells for Cells have just jointly published a ground breaking, peer reviewed, scientific publication on a novel, cost and time-saving method to generate extra-cellular vesicles (EVs) from encapsulated Mesenchymal Stem Cells (MSCs). These EVs are known to mediate many of the therapeutic effects of stem cells. The authors show that Austrianova’s proprietary Cell-in-a-Box encapsulation technology can be used to produce and deliver EVs from encapsulated MSC’s, as demonstrated using Cells for Cells proprietary MSCs. The publication, which was co-authored with their academic partners, the University of the Andes, Chile and the University of Veterinary Medicine Vienna, Austria appeared in prestigious international journal “Frontiers in Pharmacology” (Front. Pharmacol., 21 May 2020 | https://doi.org/10.3389/fphar.2020.00679 https://www.frontiersin.org/articles/10.3389/fphar.2020.00679/full)
Currently, EVs have to be purified from cell culture conditioned media using tedious, costly and time-consuming protocols that are difficult to perform under Good Manufacturing Practices (GMP) conditions. The Cell-in-a-BoxÒ encapsulation technology allows efficient enrichment of EVs at high concentration since they are released from the encapsulated cells via the semipermeable pores, which selectively enable the release of small particles but not of the MSCs. Moreover, Cell-in-a-BoxÒ provides 3D culture conditions for the MSCs. The technology can be used in cell culture allowing GMP production. Alternatively, the encapsulated cells can be implanted into patients as a retrievable delivery device that shields the cells from clearance, whilst they continuously produce EVs, growth factors, hormones and other small therapeutically relevant molecules. Moreover, the EVs produced after encapsulation can themselves be used as drug-loaded delivery vehicles. This technology will be invaluable for the treatment of regenerative diseases and Inflammatory disease.
