腸道類器官在精準醫(yī)學中的應用
發(fā)布時間:2018-11-14 18:53
【摘要】:類器官3D培養(yǎng)是一種新興的用來研究組織成體干細胞生長、分化、器官形成的體外研究系統(tǒng).目前,腸道類器官的3D培養(yǎng)是將分離的腸道隱窩或干細胞植入含有多種生長因子的基質(zhì)膠中,在基質(zhì)3D支撐下生成具有腸道上皮樣結構的微型空心球體,這些球體被稱為腸道類器官.該類器官包含有所有種類的腸道功能上皮細胞,能最大程度模擬腸道組織,故也稱之為"迷你腸".結直腸腫瘤細胞也可以利用該3D體系培養(yǎng)得到腫瘤類器官.這些腸道類器官可被廣泛應用于炎癥性腸病、腸道損傷再生、腸癌等多種腸道疾病的研究.本綜述討論了關于腸道干細胞的最新研究進展,正常類器官和腫瘤類器官的培養(yǎng),同時還將探討類器官在疾病建模和組織再生、基因修復、腫瘤個性化治療等精準醫(yī)學方面的應用.
[Abstract]:Organ-like 3D culture is a new in vitro research system to study the growth, differentiation and organogenesis of adult stem cells. At present, the 3D culture of intestinal organs is that the isolated intestinal crypts or stem cells are implanted into the matrix glue containing many growth factors, and the microspheres with intestinal epithelial-like structure are formed under the support of the matrix 3D. These spheres are called intestinal organs. This kind of organ contains all kinds of intestinal functional epithelial cells and can mimic the intestinal tissue to the greatest extent, so it is also called "mini intestine". Tumor-like organs can also be obtained by using the 3-D system in colorectal cancer cells. These intestinal organs can be widely used in the study of inflammatory bowel disease, intestinal injury and regeneration, bowel cancer and other intestinal diseases. This review reviews the latest advances in intestinal stem cells, the culture of normal and tumor-like organs, as well as disease modeling, tissue regeneration, and gene repair. Application of personalized tumor therapy and other aspects of accurate medicine.
