Fig. 2. Murine viral sequences from PDX are not from human viruses or correlated with mouse tissue contamination.

a Phylogenetic analysis of GAG genes of murine (black) and human viruses (blue). b same analysis performed for ENV genes. c Low level of reads from PDX that can be mapped to mouse reference genome. d High-level murine virus reads mapped to the MLV viral genome. e No significant correlations were found between the number of mouse-specific (x-axis) and murine viruses reads (y-axis) across all PDX samples examined (n = 184). Source data for e are provided in Source Data File.
