バイオ3Dプリンティング技術を用いた立体的細胞構造体の作製

抄録

The development of printing technology has been investigated for applications in various fields such as industry, food processing, and surgery. In the medical field, transplantation is performed for patients with serious conditions, but a shortage of donors for such surgeries has been a serious problem in recent years. As a solution to this issue, development of a new treatment is urgently required. Printing technology, in particular, is being developed for the manufacture of tissues and organs in the field of tissue engineering. Recently, a "bio-three-dimensional (3D) printer," which uses biomaterials such as cells or biopolymers, has drawn much attention in this area. This review will introduce fabrication methods for cell constructs produced by bio-3D printing that we invented in our laboratory. We have achieved good results, such that we expect to be able to make cell constructs in the form of organs such as cartilage, blood vessels, and liver tissue. We consider the potential for producing transplantable organs for patients using their own cells with our system in the near future.
