Time course of appearance and maintenance of P-bodies in the cytoplasm of uninfected and infected cells. HeLa cells grown in 4-well slides were either mock-infected (white bars) or infected with 20 pfu per cell of HSV-1(F) (black bars), or ΔU_L41 mutant virus (gray bars). The cells were fixed and stained at the times indicated. The cells were counted in 10 randomly chosen fields. The percentages of cells exhibiting visible P-bodies were counted and shown as a percentage of total cells counted as indicated in parentheses.
