To assess if the Cebpa and Gata2 mutant mouse model was comparable with human AEL we performed flow cytometry of human AEL patient samples, observing the presence of both myeloid (CD33+) and erythroid (CD71+CD235a+) blasts, as well as an expanded CD71–CD235a–CD33+KIT+CD34+ myeloid progenitor population (Figure S8B). Here, KIT is linked to acute erythroid leukemia.
