项目摘要
In the period of 2003We advanced the culture system of cell clusters isolated from the muscle layer of the mouse small intestine and confirmed that the cell cluster kept its original characteristic features in vitro. Using this method we isolated interstitial cells of Cajal(ICC) and immunize to rats to make a monoclonal antibody. We established the clone to produce antibody(AIC). This antibody is suitable for morphological studies because immunoreactivity was stable for paraformaldehyde fixation, and we applied for a patent. We plan to identify the epitope binding to AIC. Dr.Nakayama also advanced the study of pacemaker mechanism using this culture system.In the period of 2004The other culture system using mouse ES cells was studied and analyzed the formation of gut-like structures. We showed that formation process of gut-like structures mimicked the gut organogenesis, and several transcription factors crucial for the development of endoderm and gut organogenesis were expressed as a similar manner to mouse embryo. We plan to study differentiation of smooth muscles and ICC using this culture system.
2003年,我们改进了从小鼠小肠肌层分离的细胞团的培养体系,并证实细胞团在体外仍保持其原有的特征。利用该方法分离了Cajal间质细胞(ICC)并免疫大鼠制备单克隆抗体。我们建立了生产抗体(AIC)的克隆。该抗体适合形态学研究,因为多聚甲醛固定的免疫反应性稳定,我们申请了专利。我们计划鉴定与 AIC 结合的表位。 Nakayama博士还利用该培养系统推进了起搏器机制的研究。2004年期间,对使用小鼠ES细胞的另一种培养系统进行了研究并分析了肠状结构的形成。我们发现,肠样结构的形成过程模仿了肠道器官发生,并且对内胚层发育和肠道器官发生至关重要的几种转录因子以与小鼠胚胎相似的方式表达。我们计划使用该培养系统研究平滑肌和 ICC 的分化。
