LMO2 and TAL1 expression in pediatric T-ALL. Relative expression levels of LMO2 (A) and TAL1 (B) as percentage of GAPDH expression levels for 59 pediatric T-ALL patients (DCOG cohort). Patients were divided into 2 maturation stages according to their cytoplasmatic TCRβ (Cytβ) and membrane CD3 (mCD3) expression. Median expression levels are indicated by horizontal bars.
