Lastly, classes in the CAACB analyze, applied to emerging biotech products, lead us to conclude the viral safety of some ATMPs rely almost solely on avoiding contamination with the use of arduous procedure controls.
In comparison, for your human and primate cell strains, the producing operators or cell line alone were being suspected for being the source. The fact that operators are only indicated like a source with the contaminant in human or primate mobile culture instead of in CHO mobile society is probably going due to the ‘species barrier’ for viral infection involving human or primate cells over the just one hand and rodent cells on one other.
