| Outline of Final Research Achievements |
Bioprinting has attracted increasing attention as a useful tool for fabricating 3D constructs containing cells in the fields of tissue engineering and regenerative medicine. Especially, we focused on the development of novel bioinks for inkjet-bioprinting. In this study, we revealed the required conditions in the development of novel bioinks based on the study for the measurements of properties of polymer solutions and generation of satellite droplets during ejecting the polymer solution from an ink-jetting needle. We also revealed that our approach enables to use varieties of polymer solutions resulting in the hydrogels with different properties, such as the derivatives of hyaluronic acid and gelatin, without giving severe damage to the cells enclosed in the resultant three-dimensional constructs.
