Researchers discovered that epithelial cells use electricity to expel weak, energy-poor neighbors and maintain tissue health.

Every day, your body replaces billions of cells—and yet, your tissues stay perfectly organized. How is that possible? A team of researchers at ChristianaCare's Helen F. Graham Cancer Center & Research ...

University of Minnesota researchers are using 3D printers to produce "realistic human tissue" for use in medical training. Why it matters: Practicing surgical techniques and other procedures on (close ...

In situ bioprinting, which involves 3D printing biocompatible structures and tissues directly within the body, has seen steady progress over the past few years. In a recent study, a team of ...

Small 3D-printed liquid capsules inserted between layers of tissue burst open, mimicking blood, when surgeons make an incision. Budding surgeons may soon train on stretchy, lifelike 3D-printed skin ...

Scientists have mapped underappreciated scaffolding cells in skin, known as fibroblasts. They show for the first time how fibroblasts go 'rogue' in many different diseases affecting multiple organs – ...

For the first time, tiny bits of plastic have been found in the body tissue of Pacific walruses, lodged in the animals’ muscles, blubber and livers. The findings, from a University of Alaska Fairbanks ...

A walrus is seen in Alaska's Chukchi Sea in June of 2010. Research by a University of Alaska Fairbanks student found microplastics, mostly tiny fibers, were lodged in muscle tissue, blubber and livers ...
