As a professor in the bioengineering department at the University of Massachusetts in Dartmouth, Tracie Payne Ferreira ’90 has her dream job. Not only does her work help to advance healing medical technology, but she also engages students with her passion for hands-on teaching.
Ferreira’s lab researches tissue engineering. “Basically, we want to be able to take cells and grow new organs to help people, since transplants are hard to come by,” she says. “Skin is also a tissue we can grow using cell therapies that can help people heal faster and recover from chronic wounds that won’t heal. We already can synthesize cartilage, so once we get it figured out in the lab we can get it into trials for patient use.”
She adds, “A big challenge in tissue engineering is this: while you are creating a specific tissue, what do you grow stem cells on? You need something called a scaffold to hold them in place, but at the same time as the cells grow into tissue, the scaffold should dissolve so you don’t have a strange material left in the middle of the new tissue.” [Read more...]
