Can you grow a human bone outside the human body? The answer may soon be yes. Nina Tandon explores the possibility by examining how bones naturally grow inside the body, and illuminating how scientists are hoping to replicate that process in a lab. [Directed by Barry Chapman, narrated by Nina Tandon].

As humans live longer than ever before, we need our implants to last as long as we do, says bioengineer Nina Tandon. Using stem cells and digital fabrication, she's working on growing anatomically precise spare parts for the human body, replacing damaged bones, cartilage and more with implants that fit perfectly and hold up for a lifetime.

Tissue engineer and TED Fellow Nina Tandon is growing artificial hearts and bones. To do that, she needs new ways of caring for artificially grown cells -- techniques she's developed by the simple but powerful method of copying their natural environments.

Each of our bodies is utterly unique, which is a lovely thought until it comes to treating an illness -- when every body reacts differently, often unpredictably, to standard treatment. Tissue engineer Nina Tandon talks about a possible solution: Using pluripotent stem cells to make personalized models of organs on which to test new drugs and tre...

Today, around 75% of people acquire parts of their bodies that they were not born with, and This wouldn't be a problem, except that we injure ourselves earlier in life and live longer - and synthetic implants fail the sooner we get them. These substitutes need to last a lifetime, and for this reason, tissue engineers are working on developing li...
