Fig. 4. Effect of chronic zinc deficiency on bone marrow hematopoietic composition in mice at d 50. Bone marrow of ZA and ChrZD mice were individually phenotyped to identify five marrow populations: erythroblasts (CD31^–Ly-6C^–), lymphocytes (CD31⁺Ly-6C^–), granulocytes (CD31^–Ly-6C⁺), monocytes (CD31^–Ly-6C⁺⁺), and committed progenitors (CD31⁺Ly-6C⁺). Graphics represent the percentage composition for each population in the marrow with mean ± SD values given. ZA n = 7, ChrZD n = 8. *significantly different from ZA mice, p < 0.05."
