Ikoma-Anraku Lab
Machine-translated · View original
A lab that creates materials that work inside the body, leading to the regeneration of bone and cells.

AboutAbout the lab
Creating treatments from materials that blend in with the body.
The Ikoma-Anraku Lab studies how to create materials for medical use by combining inorganic and organic materials.
The lab makes artificial bone shaped for each patient with 3D printers, and develops materials that regenerate the cornea from fish scales.
It is also developing mechanisms that use drug-loaded nano-sized capsules to deliver drugs to targeted cells at the targeted time.
Combining this work with computational science and biotechnology, the lab aims to understand phenomena from the side of the living body and feed that understanding back into materials development.
Key terms
- Biomaterial
- A material made for use inside the body. It is used for artificial bone, artificial membranes, and more.
- Nanomedicine
- Medicine that uses nano-sized materials to detect or treat disease.
- Apatite
- A crystal made of calcium and phosphorus that is the main component of bones and teeth.

ResearchResearch themes
The lab combines inorganic and organic materials to create biomaterials useful in medicine. Its work is broad, ranging from materials design that learns from nature to nanomedicine that performs diagnosis and treatment at the same time.
*Illustrative imageArtificial bone made with 3D printers
With a 3D printer, powder of bioceramics, the raw material for artificial bone, can be formed into any shape. The lab makes tailor-made artificial bone shaped for each individual patient, as well as printed objects that contain drugs.
*Illustrative imageRegenerating real bone and osteochondral tissue
The lab uses collagen and apatite obtained from fish, which carry no concern about viruses shared between humans and animals. It is developing artificial materials that can reproduce real bone and osteochondral tissue.
*Illustrative imageMaterials that learn from biological fibers
The cornea of the human eye and fish scales both consist mainly of collagen fibers, and their structures are almost the same. The lab studies scales to create materials that regenerate the cornea, and is also developing strong membranes that can substitute for skin and mucous membranes.
*Illustrative imageMaterial design that manipulates cells
Materials placed in the body interact with the surrounding cells and the extracellular matrix. By finely controlling the surface properties of materials, the lab develops materials that resist blood clotting and materials that guide cell differentiation.
