mature B cell

1

In most mature B cell tumor , the chromosomal transposition could led to Juxtaposes of oncogenes and the regulatory sequences of normal expressed gene ( mostly Ig gene ) . And this Juxtaposes led to deregulation of translation .

在多数成熟B细胞肿瘤，染色体的转位引起癌基因与成熟B细胞正常表达基因（多为Ig基因）的调节序列（Juxtapose）对合，造成翻译失调。
2

The positive rate of Flt-3 expression in undifferentiated cell line was prominently higher than that in mature B cell ALL ( P < 0.05 ) .

未分化B细胞系Flt-3基因表达阳性率明显高于成熟B细胞ALL（P<0.05）。
