a
FCV stocks concentrated via ultrafiltration were diluted in complete Dulbecco's modified Eagle's medium with 5% low-endotoxin (<10 EU/ml) fetal bovine serum.
b
The data are expressed as means ± SDs from 15 replicates in 3 independent experiments. Values with different letters in the same column are significantly different (P < 0.05).
