The exact same BM smears have been then scored for presence of erythroid precursors. No considerable difference was detected within the percentage of pro-erythroblasts (mean D of total cells: healthy: four.1.two; L NB: 4.5.8; M NB: four.6.5), baso-erythroblasts (wholesome: 14.2.6; L NB: 17.7.8; M NB: 15.four.7) and poly-chromatophilic erythroblasts (healthful: 38.two.4; L NB: 39.5.eight; M NB: 41.40), whereas the percentage of ortho-chromic erythroblasts was substantially greater in healthy young children (43.2.8) than in sufferers with localized (38.60.1, p=0.01) and metastatic (36.91.7, p=0.04) NB (Figure 1B).Maturation of erythrocytes is altered in BM from NB patientsTo confirm the information obtained in BM smears suggestive of a selective impairment of late stage erythrocyte maturation, we collected BM aspirates from 16 NB individuals (Table 1, flow cytometry) and ten healthier subjects and analyzed them by flow cytometry for percentage of monocytes, neutrophils and stage II/III erythroblasts.
