TED精选演讲 | 组织工程学能创造出个性化的药物吗?

小白老师2016/10/31英语学习

摘要: 组织工程学通过利用多功能干细胞构建个性化的器官模型,用于在体外测试药物反应,从而实现针对个体差异的精准医疗。这种方法有望克服传统标准化治疗因个体反应差异而导致的疗效不确定性。Nina Tandon等研究者正探索结合生物电信号与组织工程,开发可植入“备用器官”及疾病模型,推动个性化药物发展。

  • 每个人的生理反应不同,标准化药物治疗效果常不可预测,亟需个性化解决方案。
  • 组织工程学利用多功能干细胞制造患者特异性的器官模型,用于药物测试和疾病研究。
  • Nina Tandon的研究聚焦于电刺激在引导细胞分化和构建功能性组织中的作用。
  • 个性化器官芯片可将个体药物反应数据数字化存储,为精准医疗提供新路径。
  • 该技术不仅用于药物筛选,未来还可能生成可移植的‘备用器官’。

小白老师说:我们每个人的身体是独一无二的。这是个令人愉快的想法,但面对疾病治疗时并非如此。对于标准化的治疗方法,每个个体反应不同,而且常常不可预知。组织工程学家Nina Tandon讨论了一个可能的解决办法:使用多功能干细胞制造出个性化的器官模型,在其上测试新的药物和治疗方法,并且将这些信息存储在电脑芯片上。这就是完全个性化的药物。**

Why you should listen

Nina Tandon studies electrical signaling in the context of tissue engineering, with the goal of creating “spare parts” for human implantation and/or disease models. After receiving a bachelor’s degree in electrical engineering from Cooper Union, Nina worked on an electronic nose used to “smell” lung cancer as a Fulbright scholar in Rome. She studied electrical stimulation for cardiac tissue engineering at MIT and Columbia, and now continues her research on electrical stimulation for broader tissue-engineering applications. Tandon was a 2011 TED Fellow and a 2012 Senior Fellow. Nina was also honored as one of Foreign Policy’s 2015 Global Thinkers.

About the Speaker Nina

Nina is a tissue engineer at Columbia University, adjunct professor of Electrical Engineering at Cooper Union (teaching a “Bioelectricity” course), and certified yoga instructor. Her research involves the use of electrical signalling for directing cell differentiation. In parallel, she is also pursuing her interest in scientific entrepreneurship and leadership via an executive MBA at Columbia. Check out www.ninatandon.com for more info!

She began her career in telecom at Avaya Labs, designing enterprise communications software, spent one year as a Fulbright Scholar in Rome, Italy, working on an electronic nose used to “smell” lung cancer, and then completed her PhD at MIT and Columbia, studying electrical stimulation for cardiac tissue engineering. After spending a year as an associate at McKinsey, she is now continuing her research on electrical stimulation for broader tissue engineering applications.

In her spare time, Nina practices yoga, meditation, running, throwing surprise parties, metal-smithing, playing with puppies, baking, and putting on a backpack to explore.

常见问题

什么是组织工程学在个性化药物中的应用?

组织工程学通过从患者自身细胞培养微型器官模型(类器官或器官芯片),在体外模拟其对药物的反应,从而为该患者定制最有效的治疗方案。

为什么标准化治疗对不同人效果不同?

由于基因、代谢、免疫系统等个体差异,同一种药物在不同人体内可能产生截然不同的疗效或副作用,因此需要个性化测试手段。

Nina Tandon在组织工程领域的主要贡献是什么?

她研究电刺激如何引导干细胞分化为特定组织(如心肌),并致力于将工程学、生物学与临床医学结合,开发可用于药物测试和移植的生物人工组织。

器官芯片如何帮助药物研发?

器官芯片是在微流控芯片上构建的微型人体组织模型,能更真实地模拟人体反应,提高药物筛选效率,减少动物实验,并支持个性化用药测试。
