随后,团队利用该模型,模拟了一种极为罕见的遗传性胃病:磷酸甘露糖酶2相关性高胰岛素血症伴多 囊肾病和炎症性肠病(PMM2-HIPKD-IBD)。部分患儿除血糖与肾脏异常外,还伴有胃窦小凹增生 ——即胃黏膜出现异常增生组织,可能引发出血、炎症,甚至增加癌变风险。这些病变源于胃细胞功能 紊乱,过去难以深入研究。 如今,借助患者自身干细胞培育出的"迷你胃",团队不仅能验证致病假设,还可高效筛选潜在药物,大 幅缩短新疗法从实验室走向临床的时间。 研究团队从患者胃组织中提取干细胞,在特殊培养条件下引导其发育成模拟真实胃功能的类器官。他们 分别培育出对应胃底、胃体和胃窦的三种独立类器官,再将其巧妙"组装"为一体,形成多功能整合结 构。这在国际上尚属首次。 来源:科技日报 这个"迷你胃"各部分不仅保留了原区域的生物学特征,还能像真正的胃一样相互协作,甚至能分泌胃酸 ——这是实现食物消化的关键一步。 科技日报记者 刘霞 团队认为,该"迷你胃"高度还原了胃窦至胃底的结构与功能,尤其在揭示罕见胃病机制方面展现出独特 优势。 来自英国伦敦大学学院和大奥蒙德街儿童医院的科学家携手,培育出全球首个包含完整关键结构的"迷 你胃"。这个仅 ...
