Description

The mission of our lab is to fill the gap between clinical practice and basic science through translational research. Our key research area is cardiovascular tissue engineering using 3D printing/ bioprinting technology. Please see http://hibinolab.com/.

Specific Aims

First, we aim to use innovative and novel tissue engineering approaches to regenerate the heart using 3D cardiac engineered tissues. The second focus of our lab is patient-specific vascular tissue engineering using 3D printing technology. Our ultimate goal is to create a new history to apply these basic researches into clinical fields to improve patient's quality of life.

Methods

First focus is to 3D bioprint cardiac patches without biomaterials, and characterize them using a variety of techniques, such as histology, immunohistochemistry, electrophysiology, biomechanics. Another focus of the Hibino lab is tissue-engineered vascular graft (TEVG) research. TEVGs offer the potential to overcome thrombogenicity, immune responses causing functional deterioration, and lack of growth potential by providing a biodegradable scaffold on which a patient's own cells can proliferate and provide physiologic functionality. We investigate the conditions necessary to create the ideal TEVG, using a combination of cutting edge fabrication tools and polymers/biomaterials, as well as the mechanism of neotissue formation. Recently, by combining axial imaging technology, computer-aided design, computational flow dynamics and artificial intelligence, with advanced 3D printing and biomaterials, we have created preoperatively designed, patient-specific TEVGs, that have the potential to improve surgical outcomes.
