Adaptation to a specific cell type limits replication of MV. Replication kinetics of MVs in PBMCs (A), in Vero cells (B), in Vero/CD150 cells (C), in B95a cells (D). For each experiment, 105 cells were infected at a MOI of 0,1. Each time point consists of the mean of 2 independent experiments. Vero/CD150 cells were used for the titration.
