英国科学家首次在实验室培养出功能完整的食管，并移植到猪体内，成功恢复了其正常吞咽功能。这项成果被视为器官替代工程领域的重要进步，为未来 5 年内启动人类临床试验奠定了坚实基础，有望彻底改变食管闭锁患儿的命运。食管闭锁是一种严重的先天缺陷，患儿出生时食管与胃部未能连接。全球每年约有 180 名新生儿受此困扰。当前标准治疗方案是通过复杂手术进行重建，但医生常需截取患儿肠道或上提胃部来替代食管。这不仅创伤大，还可能导致终生呼吸、消化问题及远期并发症风险。为应对这一难题，英国大奥蒙德街医院与伦敦大学学院研究团队取得了突破。他们开发了一套创新的生物工程工艺：首先以猪食管为“支架”，经过去细胞化处理，剥离其所有原始细胞，仅保留纯净的天然微观结构框架；随后，团队从受体猪身上获取微小肌肉活检样本，提取肌肉前体细胞，在实验室中大量扩增后，将其注入支架内部。整个结构在生物反应器中培养约两个月，其间持续灌注营养液，模拟体内环境，促使细胞定居、增殖，最终形成一段活的、由受体自身细胞构成的新食管。团队将实验室培育的 8 个食管移植到猪体内，所有受体猪在术后关键 30 天均存活。
