Biorelated Chemistry Lab
Machine-translated · View original
A biorelated chemistry lab that creates, from a chemistry perspective, the materials on which cells grow.
AboutAbout the lab
Using chemistry to make materials that grow cells.
The lab of Associate Professor Kazutoshi Iijima in biorelated chemistry studies materials for biomedical engineering and regenerative medicine.
As materials that serve as a foundation for cell growth (cell scaffolds), the lab works with hydrogels made from substances such as gelatin.
It has also worked on three-dimensional cell culture using silica nonwoven fabric.
The lab is developing materials that adjust the environment around cells, such as gels whose properties can be changed with light and collagen gels in which cells are aligned using flow.
Key terms
- Hydrogel
- Hydrogel: a soft polymer material that contains a lot of water and holds its shape. Cells can be encapsulated inside it.
- Cell scaffold
- Cell scaffold: a material that serves as a foundation to which cells attach and on which they grow. It is used when culturing cells for regenerative medicine.
- Nonwoven fabric
- Nonwoven fabric: a sheet-like material made by entangling fibers without weaving them.

The lab studies, from a chemistry perspective, materials for growing cells. It works with gelatin and collagen hydrogels as scaffolds for cells.
*Illustrative imageCell scaffolds whose properties change with light
The lab makes gelatin hydrogels that break down when exposed to light, and studies them as scaffolds in which light can be used to adjust how cells attach and spread. It has applications in regenerative medicine in view, such as cell migration and models of vascular tissue.
*Illustrative imageThree-dimensional cell culture using nonwoven fabric
The lab has studied the use of nonwoven fabric, made of entangled fibers, as a scaffold for growing cells in regenerative medicine. It has also worked on three-dimensional cell culture using silica nonwoven fabric and on the fabrication of three-dimensional skin models.
