Effect of HHV-7 on CB CD34–derived erythroid cultures.

Data are expressed as means ± SD of 4 to 7 independent experiments performed in duplicate. (A) Phenotypic analysis of surface glycophorin A was performed at various time points of liquid culture on erythroid cells infected or mock-infected with HHV-7. The surface expression of glycophorin A was analyzed by FACS and reported as the percentage of positive cells. (B) Viable cell counts performed at the time indicated by trypan blue dye exclusion.
