Genetic ‘switches’ could program 3D-printed bone tissue for blood vessel growth

An interdisciplinary team of engineers and chemists at Penn State has laid the groundwork to 3D print spheroids — tiny clusters of living cells — capable of regenerating bone tissue in response to severe trauma or infections. The process layers the fundamental building blocks of an organ tissue, known as bioprinting, and can create cell clusters optimized to support bone tissue regeneration.
