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。

In vitro culture showed that 10% BMSCs changed from fusiform shape to multipolar shape.

在体外培养时细胞中有百分之十的BMSC由梭形变成多极化形状。

Bone marrow MSCs are multipotent tissue stem cells that can be induced in vitro to differentiate into mesenchymal and non-mesenchymal cells.

骨髓MSC是一类存在于骨髓中的具有多向分化潜能的干细胞，体外不仅可以分化为间充质类细胞，而且可以分化为非间充质类细胞。

In this article, the latest progress in the study of DNA condensation in vitro induced by multivalent cations is reviewed covering the mechanism, process, influencing factors of DNA condensation and its recent applications in gene transfection.

本文综述了近十几年来以多价阳离子为缩合剂诱发的DNA体外缩合的研究进展，着重介绍了缩合的机理、过程、影响缩合的因素以及应用于转基因的最新成果。

AIM: To explore the effects of sterigmatocystin on IL-4 expression and secretion of murine spleen cells in vitro.

目的：探讨杂色曲霉素对体外培养的小鼠脾细胞IL-4 mRNA表达及其蛋白分泌的影响。

The rat myoblast was cultured on the surface of the scaffold in vitro.

利用扫描电镜观察平行结构支架材料吸附的L6细胞的形态学结构，观察L6细胞在材料上的表面相容性。

To determine the role of recombinant human ciliary neurotrophic factor in myogenesis, we observed the effects of rhCNTF (0－10 ng/ml) on myoblast differentiation of adult human in vitro.

为探讨外源性重组人睫状神经营养因子在成肌细胞分化中的作用，实验观察了0－10 ng/ml rhCNTF 对成人成肌细胞体外分化的影响。

Myoblast fusion is a naturally occurring process which can be achieved in vitro and provides a convenient system to study the mechanisms involved in fusion processes in general and muscle formation in particular.

Calpain-calpastatin系统对成肌细胞的细胞膜融合起着重要作用，且融合率取决于细胞中calpains与calpastatin的比例。

Objective:To seek into the mechanism of the differential adherent velocity of myoblast cultured in vitro. We assumed that this ability was not only related to the extent of maturation, but also to the physical characteristics of these cells.

目的：探讨体外培养成肌细胞差速贴壁机制，研究成肌细胞不同贴壁速度与物理性状和成熟度间的关系。

Four groups of oligonucleotides were successively cloned in pMD18-T vector to obtain four large fragments. Ligation of these four fragments resulted in a cloned DNA MgE717 coding for the 29～268 amino acid region of gE. Sequencing result showed that there is a mutation at 255 amino acid, Asn instead of Asp.

分四段分别合成，基因拼接得到了改造后的基因片段MgE717，经测序，除了在gE基因+763位核苷酸处存在一碱基置换，导致第255位的氨基酸残基由Asp突变为Asn，其余的序列与PrV鄂A株gE基因的氨基酸序列相符。
