Bioprinting technology successfully transplants organ tissues
Release date: 2014-07-14
Recently, researchers from the University of Sydney and other places have made great progress in the field of biological imaging of tissue and organ transplantation in humans affected by trauma and major diseases. The related research was published in the international magazine Lab on a Chip. In the article, researchers use bioprinted artificial blood vessel networks to simulate the body's circulatory system, which is important for the complex tissues of the body. Researcher Luiz said that thousands of people die every year from a series of organ transplants, and many people Suffer from the pain of losing tissues and organs.
In this study, researchers used a new technology called "bioprinting" to describe how many interconnected biofibers were "welded" to provide a model for artificial vascular tissue; then researchers used protein-rich cellular material to transform the model. After becoming a 3D printing section, the researchers finally removed the bioprinted fibers, leaving only a network of small channels contained in human endothelial cells that could self-assemble to form a stable capillary structure.
The study in this paper demonstrates that bioprinted vascular networks can better promote cell survival, differentiation, and proliferation; Dr. Bertassoni, a researcher, uses a novel bioprinting technique to create a large three-dimensional microvascular channel. It can sustain life and accurately meet the needs of a single patient.
Of course, simple recycled materials are very easy to obtain, but the real regeneration of complex and functional organs is a long-term goal for doctors and an urgent problem for patients.
