　　新SAT必读演讲：关怀工程组织

　　Nina Tandon

　　Nina Tandon studies ways to use electrical signals to grow artificial tissues for transplants and other therapies.

　　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.

　　What others say

　　“I love pointing out to my students that the cable equations we use to analyze transmission along nerves are the same ones developed for the transatlantic cable.” — Nina Tandon

　　Good morning everybody.

　　I work with really amazing, little, itty-bitty creatures called cells. And let me tell you what it's like to grow these cells in the lab. I work in a lab where we take cells out of their native environment. We plate them into dishes that we sometimes call petri dishes. And we feed them -- sterilely of course -- with what we call cell culture media -- which is like their food -- and we grow them in incubators.

　　Why do I do this? We observe the cells in a plate, and they're just on the surface. But what we're really trying to do in my lab is to engineer tissues out of them. What does that even mean? Well it means growing an actual heart, let's say, or grow a piece of bone that can be put into the body. Not only that, but they can also be used for disease models. And for this purpose, traditional cell culture techniques just really aren't enough. The cells are kind of homesick; the dish doesn't feel like their home. And so we need to do better at copying their natural environment to get them to thrive. We call this the biomimetic paradigm -- copying nature in the lab.
