CD_(10)抗原在胎儿骨髓的大多数淋巴细胞中,随着年龄的增长,CD_(10)~+细胞减少至成人骨髓仅含有核细胞数的1%以下。本文对23例儿童非恶性血液病(血小板减少症14例,全血细胞减少症4例,中性粒细胞减少症3例,淋巴细胞增多症1例,淋巴结病1例)进行了细胞形态学、末端脱氧核苷酸转移酶、免疫表型及分子遗传学检测,旨在探讨儿童非恶性血液病骨髓中幼稚B-前体细胞比例增加的临床及
In most of fetal lymphocytes, the number of CD10 (10) antigens decreases to less than 1% of that of adult bone marrow with age. In this paper, 23 cases of children with non-hematological malignancies (thrombocytopenia in 14 cases, 4 cases of pancytopenia, neutropenia in 3 cases, 1 case of lymphocytosis, 1 case of lymphadenopathy) were morphological, Terminal deoxynucleotidyl transferase, immunophenotyping and molecular genetic tests to explore the non-hematological malignancies in children with bone marrow in naive B-precursor cells increased the proportion of clinical and
