Epifluorescence analysis of mouse 3T3 cells permanently expressing human exon 1 (a,c,e,g) or 1′ La mRNAs (b,d,f,h). The cells were infected with herpes simplex virus type 1 strain ANG. (i,j) Untransfected mouse 3T3 cells. The cells were obtained 1 h post-infection (p.i.) (a,b,i) or 4 h p.i. (c,d,j), or 8 h p.i. (e,f) or 24 h p.i. (g,h).
