What to know about Regenerative Medicine

Researchers at the University of Notre Dame and Harvard Medical School have developed a hybrid bioprinting technique that uses extrusion and aerosol jet printing to create vascular networks with capillary-scale resolution. The system incorporates machine learning to optimize printing parameters, aiming to eventually produce functional lab-grown organs and improved drug-testing models.

What happened

Hybrid bioprinter creates capillary networks narrower than 10 micrometers Sadie Harley Scientific Editor Robert Egan Senior Editor More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10…

Why it matters

Even if the transplant is carried out successfully, recipients must take immunosuppressive medications, elevating their risk of broader infections, and adhere to a strict lifestyle for the rest of their lives—all while facing the possibility that their body…

Common ground

Scientists have been aiming to bioprint tissues and organs from a patient's own cells for decades in an attempt to solve this problem.
