This cell is CD11b-positive and has fine azurophil granules. BTO:0004657 FMA:83551 Morphology: Mononuclear cell, diameter 14-18 _M, fine azurophilic granules; markers: CD11b (shared with many other myeloid cells); location: Adult: bone marrow; Fetal: Liver, Yolk Sac; role or process: hematopoiesis, monocyte development; lineage: hematopoietic, myeloid. cell 单核细胞系中的前体细胞，是成单核细胞和单核细胞之间发育的中间细胞。该细胞是CD11b阳性的，并且具有优良的嗜酸性粒细胞颗粒。 形态学：单核细胞，直径14-18µM，细嗜晶粒细胞；标记物：CD11b（与许多其他髓样细胞共享）；位置：成人：骨髓;胎儿：肝，卵黄囊；作用或过程：造血，单核细胞发育；血统：造血，髓系。 细胞 myeloid cell 骨髓细胞 monopoietic cell 单核造血细胞 monocyte differentiation 单核细胞分化 azurophil granule 嗜苯胺蓝粒 integrin alpha-M 整联蛋白α-M
