Name SAKAGUCHI Katsuhisa
Official Title Associate Professor
Affiliation Medical Engineeing
Profile Katsuhisa Sakaguchi is conducting research in the field of regenerative tissue engineering, which is an interdisciplinary area that combines medicine, science, and engineering. His primary objective is to utilize bioengineering techniques to create three-dimensional tissues, thereby contributing to the resolution of medical and food-related challenges and paving the way for a new future society. His research interests revolve around the development of devices for mass cell expansion, vascular network perfusion devices for the construction of three-dimensional tissues, and devices for evaluating the quality of regenerated tissue.
Research Field(Keyword & Summary)
  1. (1) Regenerative medicine

    We are conducting research to create three-dimensional tissues and organs from stem cells. With this regenerated tissue, we aim to treat diseases that have been incurable until now.

  2. (2) Cell Based Food (Cultured Meat)

    We aim to produce meat derived from cells. Food produced from cells is a product with reduced waste and lower environmental impact, targeting sustainable food production.

  3. (3) Bioreactor

    To create regenerated transplantable tissues and cultured meat, we are developing a method for mass cell amplification and a perfusion device for constructing three-dimensional tissue organs.
