While overall engraftment was similar between NOTCH1High and NOTCH1Mutated transplanted samples (Figure 5A), FACS analyses revealed an expansion of CD45+CD34+CD2+CD7+ and CD45+CD34+CD2+CD7− populations in NOTCH1Mutated (patients 05, 08, 11, 12) and NOTCH1High (patient 02) T-ALL samples when compared with NOTCH1WT (patients 04, 09, 10) T-ALL samples and cord blood (Figure 5B). Here, PTPRC is linked to acute lymphoblastic leukemia.
