摘要蛋白转导是将具有生物学活性的目的 片段与蛋白转导结构域相连接,然后导入细胞中并发挥其生物学效应的一项技术.蛋白转导结构域是一种小分子多肽,不仅具有穿透细胞膜的功能,同时也能够保持其融合蛋白的活性.蛋白转导技术是一项新兴的生物学技术,自从这项技术发明以来,被广泛的应用到了细胞基因调控的各个方面.本文以Tat、Pdx-1、Beta2/NeuroD转导蛋白为例,综述蛋白转导技术在胰腺干细胞分化中的应用.

abstractsAs a new biotechnology, protein transduction connects the target fragment with biology active and protein transduction domain, and transducer it in to cells, exert its biological effects. Protein transduc-tion domain is a small molecule peptide, not only the protein transduction domain can penetrate through cell membrane, but could maintain the activity of its fusion protein. Protein transduction is an emerging biology technology, it has been applied into all aspects of cell gene regulation since its invention. In this article, we take Tat, Pdx-1 and Beta/NeuroD for instance and review the application of transduction protein in the dif-ferentiation of pancreatic stem cell.
