Few suspension cells can be used for vaccine manufacturing today as they either do not meet requirements from health regulatory authorities or do not produce high virus titres. Two new avian designer cell lines (AGE1.CR and AGE1.CR.pIX) that have been adapted to grow in suspension in serum-free medium were evaluated for their potential as host cells for influenza and modified vaccinia Ankara (MVA, wild type) vaccine production. Their metabolism was studied during growth in static (T-flasks) and dynamic cultivation systems (roller bottles, stirred tank reactor, wave bioreactor). High cell concentrations up to 5.8x10(6)cells/mL were obtained with doubling times of 23h for AGE1.CR and 35h for AGE1.CR.pIX, respectively. Both viruses were produced to high titres (3.5 logHA/100 microL for influenza virus, 3.2x10(8)pfu/mL for MVA). Hence, the CR cell lines are an appropriate substrate for pharmaceutical influenza and MVA production.
