To assess CD44 relation with T-ALL blasts' maturational profile, we compared immature T-ALL cases with mature T-ALL cases, and observed a higher CD44 expression in mature cases (MFI 57.5 [2.7–866.3], compared to MFI 26.2 [1.9–1239] ; p = 0.013; Figure 2D). Here, CD44 is linked to acute lymphoblastic leukemia.
