三维类器官展现发育中肢体关键特征 为人体组织修复提供新思路
Ke Ji Ri Bao· 2025-12-04 00:55
以往大多数与肢体相关的类器官模型仅关注中胚层,忽略了AER和其他皮肤细胞(表层外胚层)在肢体 形成中的指导作用。此次为制造"布多伊德",研究团队从小鼠胚胎干细胞中培养出混合细胞群,这些细 胞自然形成了类似AER、表层外胚层和中胚层细胞,基本涵盖了发育中肢体的所有主要细胞类型。当这 些细胞被聚合时,它们能够自我组织成三维结构。团队随后利用该系统研究AER细胞是如何引导组织形 成的。 "布多伊德"提供了一种全新的实用系统,使人们能够探索胚胎发育中难以深入研究的领域,例如细胞如 何协调行为、早期结构如何发育以及软骨如何形成。其应用不仅限于基础研究,未来还将涉及先天性疾 病建模、测试可能损害肢体发育的化学物质,甚至促进再生医学的应用。 瑞士洛桑联邦理工学院一组团队利用干细胞制造了全新三维类器官——"布多伊德"。这种类器官展现了 发育中肢体的多个关键特征,包括对称破缺(塑造肢体的第一步)和早期软骨形成。该研究发表在最新 一期《科学进展》杂志上。 在胚胎早期发育阶段,身体器官的构建依赖于不同细胞类型之间化学信号的交换。以肢体发育为例,肢 体表面一层被称为"顶端外胚层脊"(AER)的薄层皮肤细胞会发出信号,引导下方细胞群生 ...

科技日报北京12月3日电 (记者张梦然)瑞士洛桑联邦理工学院一组团队利用干细胞制造了全新三 维类器官——"布多伊德"。这种类器官展现了发育中肢体的多个关键特征,包括对称破缺(塑造肢体的 第一步)和早期软骨形成。该研究发表在最新一期《科学进展》杂志上。 "布多伊德"提供了一种全新的实用系统,使人们能够探索胚胎发育中难以深入研究的领域,例如细 胞如何协调行为、早期结构如何发育以及软骨如何形成。其应用不仅限于基础研究,未来还将涉及先天 性疾病建模、测试可能损害肢体发育的化学物质,甚至促进再生医学的应用。 【总编辑圈点】 "布多伊德"为生物医学研究提供了一种更符合伦理的替代方案。在这一领域,传统上高度依赖动物 实验,而全新的基于干细胞的方法能很好地重现胚胎组织的关键特征,许多曾经需要使用大量胚胎的实 验,现在都可以在受控的类器官系统中进行。这不但有助于替代和减少在发育研究中的动物使用,还将 助力药物毒性筛查并推动再生医学,为软骨等人体组织修复等提供新思路。 在胚胎早期发育阶段,身体器官的构建依赖于不同细胞类型之间化学信号的交换。以肢体发育为 例,肢体表面一层被称为"顶端外胚层脊"(AER)的薄层皮肤细胞会发出信号,引 ...
