A team of researchers from Texas A&M University’s Department of Biomedical Engineering has designed and 3D bioprinted a highly realistic model of a blood vessel.
The model is made of a newly nanoengineered, purpose-built hydrogel bioink and closely mimics the natural vascular function of a real blood vessel, as well as its disease response. The team hopes its work can pave the way for advanced cardiovascular drug development, expediting treatment approval while eliminating the need for animal and human testing altogether.
“A remarkably unique characteristic of this nanoengineered bioink is that regardless of cell density, it demonstrates a high printability and ability to protect encapsulated cells against high shear forces in the bioprinting process,” said Akhilesh Gaharwar, associate professor at the university and co-author of the study. “Remarkably, 3D bioprinted cells maintain a healthy phenotype and remain viable for nearly one month post-fabrication.”
