人类体细胞的重编程利用容易获得的组织(例如皮肤或血液)来产生胚胎样诱导多能干细胞(iPSC)。该程序已应用于来自分类为疾病组的患者的体细胞,从而创建“疾病特异性”iPSC。在这里,我们研究了从患者的单细胞创建疾病模型的挑战和假设。疾病发生和进展的动力学以及疾病在患者体内的空间定位都是模型构建的挑战。基因改造、重编程、生物材料和动物模型方面的新工具可用于应对这些挑战。
Reprogramming of human somatic cells uses readily accessible tissue, such as skin or blood, to generate embryonic-like induced pluripotent stem cells (iPSCs). This procedure has been applied to somatic cells from patients who are classified into a disease group, thus creating ‘disease-specific’ iPSCs. Here we examine the challenges and assumptions in creating a disease model from a single cell of the patient. Both the kinetics of disease onset and progression as well as the spatial localization of disease in the patient’s body are challenges to model construction. New tools in genetic modification, reprogramming, biomaterials, and animal models can be used to address these challenges.
