Fig. 3. Single-cell sequencing support the presence of murine viruses inside PDX tumor cells.

Fig. 3

a Relative proportions of murine viruses in the virome of lung cancer PDX cells are significantly higher than in the cells from the primary lung cancer samples as measured by single-cell RNA-Seq (PDX: n = 1147; non-PDX: n = 152). b, c Viral reads from single-cell sequencing of PDX-derived tumor cells cover the entire genomic region of MLV. d No single-cell sequencing reads from non-PDX control samples were observed or mapped to the viral genome. e The single-cell sequencing reads that can be mapped to the mouse reference genome are very low in both PDX-derived tumor cells and non-PDX control cells (PDX: n=9; non-PDX: n = 152). For box plots in (a) and (e), Box limits: 25th and 75th percentiles; center line: median; whiskers: 1.5x interquantile range from box limits; dots: outliers. Source data for a and e are provided in Source Data File.
