Scientists from Brigham and Women’s Hospital in Boston, Mass., have successfully used 3D-printing to replicate human blood vessels.
The experiment marks the first time that synthetic blood vessels were created, according to RT.
Blood vessels are extremely fragile, and are more delicate than anything that has been synthetically bio-printed before.
“Creating artificial blood vessels remains a unique challenge in tissue engineering,” said Ali Khademhosseini, biomedical engineer and project leader. “We’ve attempted to address this challenge by offering a unique strategy for vascularization of hydrogel constructs that combine advances in 3D bio-printing technology and biomaterials.”
“In the future, 3D printing technology may be used to develop transplantable tissues customized to each patient’s needs, or be used outside the body to develop drugs that are safe and effective,” Khademhosseini said.
