Researchers at The Pennsylvania State University have developed a new synergistic approach to revascularization that combines a new framework made from granular hydrogels with micropuncture, a surgical technique. Their preclinical method could rapidly grow organized blood vessels in live rats.

Researchers have developed sugar-coated gold nanoparticles to both image and destroy biofilms. In a study, they used the nanoparticles on the teeth and wounded skin of rats and mice, eliminating biofilms in as little as one minute and outperforming common antimicrobials.

Tissue engineering research has uncovered that a skin cell type could be a new therapeutic target to accelerate the healing of burns and possibly other wounds.

Osteoarthritis – a painful condition that results from the deterioration of the cartilage in our joints – affects millions of people worldwide. To combat this issue, NIBIB-funded researchers are developing an implantable, biodegradable film that helps to regenerate the native cartilage at the site of damage. Their study, performed in rabbits, could be an initial, important step in the establishment of a new treatment.

A new study shows how the brown anole lizard solves one of nature's most complex problems -- breathing -- with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the anole lung develops in just a few days into crude lobes covered with bulbous protuberances. These gourd-like structures, while far less refined, allow the lizard to exchange oxygen for waste gases just as human lungs do. And because they grow quickly by leveraging simple mechanical processes, anole lungs provide new inspiration for engineers designing advanced biotechnologies.

The technique used in this preclinical study could aid tissue regeneration following severe accidents, surgical resections, or progressive muscle loss due to age or genetic disease.

In a groundbreaking new study, researchers have 3D printed a functioning centimeter-scale human heart pump in the lab. The discovery could have major implications for studying heart disease, the leading cause of death in the United States killing more than 600,000 people a year.

Bioengineers print 3D implants with layered cells destined to become distinct combinations of tissue, like bone and cartilage. The scaffolds degrade over time to leave the natural tissues in place.

Paralyzing damage in spinal cord injury is often caused by the zealous immune response to the injury. NIBIB-funded engineers have developed nanoparticles that lure immune cells away from the spinal cord, allowing regeneration that restored spinal cord function in mice.

Bioengineers used bone engineered in a 3D-printed mold and grown alongside the ribs of sheep to successfully replace a portion of the animals’ jaw bones.
