TEHRAN, Dec. 25 (MNA) � Researchers in Amir Kabir University�of Technology have printed artificial blood vessels using a bioprinting machine.
Dr. Majid Halvayi�the project manager told Mehr News that they had developed the machine�s second version which was 20 per cent rapid. � bio-printers are 3D printing machines capable of printing layers of cells,� he added and pointed to his research where he and his group developed a printer to carry out the 3D printing of circular and cylindrical structures of the blood vessels.
�He first phase of the research developed bio-printer to print vessels. The laboratory model has been developed but needs testing,� he said.
�The ultimate end for developing bio-printers is to replicate body organ tissues. The research around the world has attempted to replicate critical organs like the heart, through simulating the cell structures of the body organs,� Halvayi added.
�For replicating hard tissues, 3D printing is used. For doing so, a cell scaffold is printed and then cells are mounted on the scaffold. However, in bio-printing cells are printed on the scaffolds simultaneously,� he told Mehr News.
