We are developing algorithms to design a stent, an implantable medical device that mechanically expands a stenotic lesion based on the patient's symptoms. We are working to establish a mechano-bio-design theory that feeds back the inflammatory response and other biological responses to long-term implantation into the shape design of the stent, rather than simply considering the matching of their mechanical properties.
Blood vessels play an important role in maintaining homeostasis (the maintenance of a normal physiological state) because they are essential for supplying oxygen and nutrients to every part of the body. As one of the mechanisms of this homeostasis, vascular endothelial cells, which exist in a single layer inside blood vessels, regulate vascular homeostasis by changing their own morphology and function in response to hemodynamic stimuli (fluid shear stress, cyclic stretch, and hydrostatic pressure) generated by the blood circulation. We focus on the response of vascular endothelial cells to fluid shear stress and hydrostatic pressure. We have elucidated the mechanisms that induce different cellular responses to physiological/pathological conditions and the mechanism by which cells sense hydrostatic pressure and convert it into intracellular biochemical signals.
More than 99% of the universe is filled with plasma. Because plasma is highly energetic and unstable, it is observed on Earth as limited phenomena such as lightning and auroras. Our research group is developing novel medical technologies by artificially interacting plasma with various substances. We have been able to improve cell adhesion and induce crystal structure specificity by applying plasma to proteins and sugars. These results are expected to be applied as medical adhesives and sweeteners that can be easily consumed even by diabetics.
We are developing new experimental techniques to realize "anyone can do the same". We hope to contribute to the advancement of science and technology by standardizing the parts of the techniques that previously depended on the know-how of each research group.
Ultrasound echoes, familiar from medical imaging, actually contain a wealth of information, including sound reflections, scattering, and attenuation. By carefully analyzing these signals, we can quantitatively assess the structure and properties of cells and tissues without the need for special dyes or labels (label-free). We aim to apply this technology to develop a new ultrasound-based evaluation method that allows researchers and clinicians to accurately determine the state of cells and tissues—without relying on intuition or experience—in biological and medical settings.
