Figure 2. CRLF2 overexpression is associated with reduced B cell differentiation in B-ALL patient samples.
(A) In two CRLF2-overexpressing B-ALL patient samples (DS-ALL 839 and non-DS ALL 105127-R) demonstrating both pro-B and pre-B populations, the high-CRLF2 mean fluorescence intensity (MFI) quartile demonstrated a significantly higher mean proportion of pro-B cells (p=0.024). (B) Representative flow plots showing CRLF2 overexpression correlates with a less differentiated immunophenotype in B-ALL patient samples 839 (DS) and 105127-R (non-DS).
