New Advances Push Engineered Tissues Toward 3-D

Although doctors still cannot simply order new, functioning organs for patients who need replacements, researchers in labs around the world are making the important advances in tissue engineering that set the stage for regenerative medicine as well as make other biomedical technologies possible.

Tissue Engineering and Regenerative Medicine

Medical researchers increasingly regard tissue engineering and regenerative medicine as potential game changers when it comes to repairing damage from disease or injury and restoring function. To understand the progress made and challenges ahead for this combined field, IEEE Pulse sought out two experts: David

Brain over Brawn

As much as we know about the vitamins, minerals, and types of exercise important to promoting good muscle health, many fundamental questions remain about skeletal and cardiac muscle.

Turning the Unknown into Known

Taken as a whole, rare diseases are not very rare. Even though a rare disease by definition is one that affects fewer than 200,000 Americans or fewer than one in 2,000 Europeans at any time, when rare diseases are considered together, they affect some 350 million people worldwide.

Tech Fights Toughest Tumors

Ask any surgical oncologist, and you’ll hear the same thing: tumors are insidious. Removing them completely can be very difficult. Sometimes tumors are in hard-to-reach areas, and, in many cases, tumor tissue looks so much like normal tissue that surgeons cannot tell exactly what to excise and what to leave alone.

A Glowing Future

New dyes latch only onto tumor cells, fluoresce, and show surgeons the entire tumor, including any of its elusive and meandering finger-like projections that may otherwise escape resection.
