Figure 4From: Validation of a mouse xenograft model system for gene expression analysis of human acute lymphoblastic leukaemiaComparison of ALL.100 ranked transcript cluster signal intensity to mouse non engrafted spleen (NES). Comparison of ranked ALL.100 (100% human ALL) (n = 8), shown in black, and corresponding mouse NES (n = 3), shown in grey, mean signal intensity. Transcript clusters are ranked according to descending mean signal intensity of ALL.100. A Without application of filter B Filtered, via the removal of mouse NES transcript clusters from the top 1% of normalised expression with a mean signal intensity > 7.56 (log base 2 scale).Back to article page
