Exosome Therapeutics for Regenerative Applications



About ExTherea

ExTherea is a biotechnology company founded in Kanagawa, Japan. We are investigating exosomes - nano-sized particles which are released by cells - and their use in regenerative medicine.


Specifically, we are studying exosomes derived from oral mucosa - one of the tissues in the human body with the highest capacity of regeneration. The underlying research was performed at Karolinska Institutet and Tokyo Women's Medical University.



2020-08 ExTherea was one of the five awardees for the "World Without Disease" grant from Takeda Pharmaceuticals, out of 79 applicants. The grant provides research funding (10M yen / year) and lab space for three years. Press release in Japanese. In this project we aim to develop an "exosome-loaded nasal spray" as a treatment for neurodegenerative disorders.
