HSP90AB1 and anemia (phenotype): The levels of HSP90 expression in flow cytometry in primary cells isolated from the bone marrow (BM) or peripheral blood (PB) of patients diagnosed with T- or B-ALL was higher than in hematopoietic cells (CD45+) isolated from patients diagnosed with hematological disorders other than ALL (e.g. anemia or thrombocytopenia) (Fig. 3a).
