Abstract

Stromal macrophages (M phi) have been localized in situ and isolated within erythroid clusters from human marrow. Stromal M phi arborize in an extensive network uniformly distributed throughout marrow interstitium, and express the phenotype CD4+, CD11a+, CD11c+, CD13+, CD14+, CD16+, CD18+, CD31+, CD32+, FcRI+, HLA-DR+, and CD35-, transferrin receptor-negative, and CD11b (weak). They express endocytic receptor antigens, but show significant differences in myeloid antigen expression compared with freshly harvested or cultured monocytes. Human stromal M phi are therefore specialized mature marrow M phi that are accessible for further investigations in infectious, storage, or hemopoietic disorders.

摘要

基质巨噬细胞(M phi)已在原位定位,并从人骨髓的红系簇中分离出来。基质M phi在广泛分布于整个骨髓间质的广泛网络中形成树枝状,并表达CD4 +、CD11a +、CD11c +、CD13 +、CD14 +、CD16 +、CD18 +、CD31 +、CD32 +、FcRI +、HLA - DR +和CD35 -、转铁蛋白受体阴性以及CD11b(弱阳性)的表型。它们表达内吞受体抗原,但与新鲜收获或培养的单核细胞相比,在髓系抗原表达上存在显著差异。因此,人基质M phi是特殊的成熟骨髓M phi,可用于对感染性、贮积性或造血性疾病进行进一步研究。
