3D printed blood vessels form functioning blood vessel network after implantation into mice

University of California, San Diego researchers have 3D printed blood vessels which can integrate into existing vasculature. Researchers from the University of California, San Diego (CA, USA) have utilized 3D bioprinting to create a functioning network of blood vessels. The biomimetic blood vasculature was implanted into mice and was able to integrate into the mice's own network, with the vessels branching out into a series of smaller vessels and letting blood circulate normally. Shaochen Chen and his team used a homemade printer was used to print the blood vessels layer by layer, utilizing polymers combined with live endothelial cells. From...
