胚胎发育

In this review, we provide a general background of the Pax genes, highlight the role of Pax proteins playing within specific tissues in terms of embryological development, and give a brief introduction of alternatively spliced isoforms of Pax protein identified.

文章简述了Pax基因的相关背景知识，详细介绍Pax1—Pax9调控在胚胎组织发育中的各项功能，并列举了现已确定的Pax基因在不同物种中的选择性剪接产物。

To determine whether the same molecular mechanisms are inoled in the formation process, the expression pattern of transcription factors regulating endoderm and gut deelopment in the mouse embryo was examined by in situ hybridization and compared with in io expression.

为了证明在成形过程中是否也具有相似的分子机制，我们通过原位杂交同体内表达比对的方法来检查小鼠胚胎中调节内胚层和肠道发育的转录因子的表达模式。

In this study,the expression and role of PAI-3 in the epithelization of human skin,including normal adult human skin,cultured differentiated keratinocytes and the development of human embryo,were observed,so as to elucidate the possible role of PAI-3 in the epithelization of skin and provide the experimental base for further studying the mechanism in epithelization of skin and all kinds of skin diseases.

本实验旨在研究正常成人皮肤组织及培养分化KC 中和胚胎生长发育过程表皮KC 中的PAI-3 的表达及作用，希望有助于阐明PAI-3 在皮肤上皮化中的功能，为进一步研究PAI-3 在皮肤上皮化中的机制及各种皮肤疾病提供实验基础。
