Bioprinting
Bioprinting
Bioprinting (pronunciation: /ˈbaɪoʊˌprɪntɪŋ/) is a form of additive manufacturing that involves the creation of tissue and organ structures in a layer-by-layer fashion using biomaterials and cells. The process is similar to 3D printing, but instead of using plastic or metal, it uses living cells.
Etymology
The term "bioprinting" is a combination of "bio-", a prefix derived from the Greek word "bios" meaning "life", and "printing", referring to the process of creating objects layer by layer, as in 3D printing.
Process
Bioprinting typically involves three main steps: pre-bioprinting, bioprinting, and post-bioprinting.
In the pre-bioprinting stage, a digital model of the tissue or organ to be printed is created using medical imaging techniques such as CT or MRI scans.
During the bioprinting stage, the digital model is used to guide the printer as it deposits layers of biomaterials and cells to create the tissue or organ structure.
In the post-bioprinting stage, the printed structure is matured in a bioreactor to allow the cells to grow and form functional tissue.
Applications
Bioprinting has potential applications in various areas of medicine, including tissue engineering, regenerative medicine, and drug discovery. It could also be used to create organ transplants and personalized medicine.
