We have demonstrated tissue engineering approaches in our previous works to develop tissue clearing and tissue expansion technologies.
ELAST (Entangled Link-Augmented Stretchable Tissue-hydrogel) Technology
Ku et al. (2020) Nature Methods
This technology transforms biological tissues, such as large human brain tissues, into elastic material. The transformed tissues are virtually indestructible throughout experimental procedures, facilitating large-scale 3D imaging. The beauty of the elasticized tissues is their shape transformability to enable ultra-fast molecular delivery and deep-tissue labeling via tissue-thinning.
In addition to mechanical reinforcement and ultra-fast labeling, ELAST also renders biological tissues transparent. This new form of tissue clearing technology helps researchers explore large and deep 3D architecture in tissues, particularly human tissue specimens.
MAP (Magnified Analysis of Proteome) Technology
Ku et al. (2016) Nature Biotechnology
Method of the Year 2016 in Nature Methods
25 Landmark papers in Nature Biotechnology
Park et al. (2021) Science Advances
This technology physically expands intact tissues and organs, while preserving their biomolecular content, such as proteins. The scenes of biological architecture in expanded tissues always look several times larger, enabling 3D super-resolution imaging at the tissue level.
