The cell cycle phase affects the potential of cells to replicate Autographa californica multiple nucleopolyhedrovirus.
We investigated the effect of growth phase of suspension culture of insect Sf9 cells on cell cycle phase distribution, cell viability and Autographa californica multiple nucleopolyhedrovirus (AcMNPV) production. The cell culture showed a maximum cell viability and potential to replicate the virus at the peak of G1 phase cells in the culture, while the minimum cell viability coincided with the peak of G2/M phase cells. These results indicate that the G1 phase plays a substantial role in the ability of cells to replicate the baculovirus and may help to develop a baculovirus infection dynamics model and control the expression of foreign genes.
