OBJECTIVE: To explore the mechanism of tissue specificity of neurotropism in peripheral nerve regeneration, we investigated the biological characteristics of the nerve regeneration conditioned fluids on motoneuron of SD rats cultured in vitro.

目的 比较源于运动及感觉神经的再生条件液以及碱性成纤维细胞生长因子对体外分散培养的SD大鼠运动神经元的生物学效应，探讨周围神经再生趋化特异性产生的机制。

In conclusion, Schwann cells from wallerian degenerating facial nerves of rats might bear with similar biological characteristics and functional phenotype to those from sciatic nerves in vitro, and they might be able to produce soluble NTFs for trophic support on facial motoneuron cultures. The establishment of methods for obtaining high-purity facial motoneuron cultures of rats with partially labeled fluorescence should be of significance in contribution to further investigation on facial motoneuron's response to NTFs and other affecting factors.

By retrovirus vector the foreign mdr1 gene could be efficiently transferred into bone marrow mononuclear cells of mouse in vitro, and it was confirmed that mdr1 gene was expressing stably and effectively in cells; in short terms there is no significant influence on the bone marrow MNC by transfection of mdr1 gene,but in the long run(in our study we had surveyed 2 months),there is a decline in the expression of apoptosis factor Bax in the MNC which transfected by mdr1 gene,in favour of the recovery of the receptor mouse;on the other hand it also poses a blance problem between multiplication and apoptosis in the process of receptor hematopoiesis after transplanting HSC which was transfected with mdr1 gene.

通过逆转录病毒载体可在体外将外源性mdr1基因转入小鼠骨髓单个核细胞中，转染的mdr1基因能整合到骨髓单个核细胞基因组中并有功能性表达；mdr1基因转入小鼠骨髓单个核细胞在移植后短期内对受体造血细胞没有显著影响，但从长期看来(本研究观察2个月)转染了mdr1基因的造血干细胞的凋亡因子Bax表达降低，更有利于受体鼠造血的恢复；另一个方面它也同时提出一个问题，即mdr1基因转染造血干细胞在回输受体后造血过程的增殖凋亡平衡。
