Fig. 3From: Actinobacillus pleuropneumoniae induces SJPL cell cycle arrest in G2/M-phase and inhibits porcine reproductive and respiratory syndrome virus replicationThe ≤ 3 kDa AppΔapxICΔapxIIC ultrafiltrate is sufficient to block SJPL cell cycle in G2/M-phase. a Representative experiment of SJPL and MARC-145 cell cycle profile analysis; ≤ 3 kDa DMEM ultrafiltrate as control is compared to the ≤ 3 kDa AppΔapxICΔapxIIC culture supernatant ultrafiltrate. b Distribution of cell cycle phases after SJPL cells treatments with the ≤ 3 kDa DMEM ultrafiltrate or the ≤ 3 kDa AppΔapxICΔapxIIC culture supernatant ultrafiltrate. The experiments were repeated at least 2 times. Asterisks indicated significant differences. **P ≤ 0.01, values are presented as ± SEMBack to article page
