Objective: To study the isolation and culture of chondrocyte of joint cartilage, and the influence of EGF on its growth and dedifferentiation.

目的：研究关节软骨细胞的原代分离及体外培养，了解表皮细胞生长因子(EGF)对其生长和去分化趋势的影响。

Our findings suggest that direct cell type conversion occurs via successive steps, and that dedifferentiation can occur in the absence of cell division.

我们的发现表明，细胞类型的直接转变是逐步完成的，而且这个去分化的过程能够在无细胞分裂的情况下发生。

Conclusion: the decreased expression of E-CD might be responsible for the cellular dedifferentiation, the infiltrative growth and poor prognosis of gastric carcinomas.

结论：E - CD减弱表达与胃癌细胞分化差、浸润型生长及预后较差密切相关。

It appeared that the sugarcane leaf segments dedifferentiation and callus formation induced by 2.4-d May be related with the changes of endogenous levels of zeatin, zeatin riboside and ABA.

据此我们认为在甘蔗组织培养中2.4 - D可能通过调节内源激素的水平及其相互作用，引起培养物中某些生理生化过程发生改变，从而进行脱分化和愈伤组织形成。

The effects of several factors on dedifferentiation and redifferentiation of Pueraria lobata earthnut were investigated by orthogonal experiment, single factor experiment and plant tissue culture.
