Establishment and Characterization of a High and Stable Porcine CD163-Expressing MARC-145 Cell Line

Figure 4

Growth kinetics of PRRSV in pCD163-MARC and MARC-145 cells. Growth curves of PRRSV classical strain S1 (a) and highly pathogenic strain SY0608 (b) were determined independently in pCD163-MARC and MARC-145 cells. pCD163-MARC and MARC-145 cells were individually infected with PRRSV at an MOI of 1 for 1 h. Culture supernatants were collected at the indicated times and virus titers were determined. The data represent the means of three independent experiments, with each experiment performed in triplicate. Error bars indicate the standard deviations of three experiments. P < 0.05.
