Adaptation of adherent MDCK cells to suspension growth in Xeno serum-free medium. a Viable cell concentration (black circle) and cell viability (black square) over the period of adaptation. b Cell-specific growth rate (black diamond) of MDCK cells over the adaptation. The inset in the panel is a microscopy picture showing the morphology of the adapted suspension MDCK cells. Error bars represent the standard deviation of three analytical replicates
