Hematopoietic Cancer Cell Lines Can Support Replication of Sabin Poliovirus Type 1

Figure 2

Surface expression of CD155, the receptor for poliovirus, on Vero, CHO, and hematopoietic tumor cell lines using FACS analysis. In (a) CD155 expression from a representative experiment is shown. In the right upper corner the mean fluorescence intensity levels are shown. In (b) the mean percentage of CD155 expressing cells ± SD from 3–6 independent experiments is shown.
