Takagi Lab
Machine-translated · View original
This aquaculture biology lab puts fish collagen to use in materials for regenerative medicine and in cosmetics.
AboutAbout the lab
Giving new value to the parts of fish that are discarded.
Takagi Lab researches how to make effective use of the collagen contained in fish bodies.
When fish are processed, parts such as the head, bones, and skin are discarded (by-products).
The lab aims to extract useful components from these parts and develop new products, so that fish are used without waste.
The lab also studies the farming of sturgeon, whose roe is harvested as caviar.
Key terms
- By-products
- The parts left over after fish are processed, such as the head, bones, skin, and swim bladder. Most of them are discarded.
- Collagen
- A protein abundant in skin and bones. Three chains come together in a helix and support tissue from the inside.
- Cell scaffold
- A base on which cells attach, multiply, and grow. It is essential for building artificial tissue.
ResearchResearch themes
The lab aims to clarify the function of collagen in by-products of fish processing and to apply it to developing products in medical-related fields, such as pharmaceuticals and materials for cell scaffolds. It also works on sturgeon aquaculture and on developing uses for its by-products.
*Illustrative imageMaking use of by-products from sturgeon aquaculture
In sturgeon aquaculture for caviar, most of the body left after processing (by-products) is discarded. The lab aims to develop uses for these by-products and leave nothing to waste (zero emission).
*Illustrative imageFish collagen as a cell scaffold
Focusing on collagen's ability to promote tissue repair and regeneration, and its ability to form three-dimensional structures that serve as scaffolds for cells, the lab aims to develop medical products using fish collagen.
