1117-人视网膜类器官修复大鼠视神经横断损伤
from 聊聊Sci
这项研究探讨了利用人视网膜类器官(hRO)修复大鼠完全断裂的视神经。通过一种名为 hROITON 的创新手术,研究人员将类器官植入神经断端,成功建立了中继式的神经连接。实验结果显示,受体大鼠在术后实现了部分视觉功能恢复,包括瞳孔对光反射和视觉引导行为。通过化学遗传学手段抑制类器官活性后,这些恢复的视觉反应随之减弱,证明了功能重建依赖于移植物的神经活动。此外,解剖学分析证实,宿主轴突通过类器官形成了跨越损伤部位的神经解剖连续性。该成果为治疗严重视神经损伤提供了一种基于宿主-移植物耦合的新型转化医学方案。References:Gong Y, Zhu H, Ge L, et al.
