The Researchers 3D Biological Printing Tubular Structure, Simulation Of The Blood Vessels And Ducts
Aug 28, 2018

Many diseases tubular tissue damage: arteritis, atherosclerosis and thrombosis, damaged blood vessels and urinary epithelial tissue may suffer from inflammatory lesions and harmful congenital abnormalities.


Researchers have found that they can print out the mimic vascular tissue and urinary tract epithelial tissue.They will be urothelial and bladder smooth muscle cells mixed with water gel, urinary epithelial tissue.In order to print the vascular tissue, their user endothelial cells, smooth muscle cells, and a mixture of water gel.

Print tube with different size, thickness and properties.Zhang said, the complexity of biological print organization structure is very important for the feasibility of it as a natural tissue substitutes.That's because natural organization is very complex.Blood vessels, for example, is composed of multilayer, and multilayer is composed of a variety of cell types.

The team plans to continue the preclinical study to optimize biological ink composition before test safety and effectiveness and 3 d printing parameters.

"We are currently further optimized parameters and biological materials," zhang said."Our goal is to create a sufficient mechanical stability of tubular structure, in order to maintain the body."

The team on August 23, is published in the Advanced Materials on paper describes its new methods and results.
