J-TEC's efforts to industrialize regenerative medicine in Japan

Abstract

J-TEC was launched in 1999 to industrialize regenerative medicine in Japan. We developed the first regenerative medicine product, JACE (autologous cultured epidermis), which received PMDA approval for treating serious burns in 2007. Then, JACC (autologous cultured cartilage), the second product, was approved in 2012 for efficacy on traumatic cartilage defects. In 2014, the Pharmaceutical Affairs Law was revised to the Pharmaceutical and Medical Device Act, and regenerative medicine products, including gene therapies, were newly classified to accelerate productization. Subsequently, Nepic (autologous cultured corneal epithelium) and Ocural (autologous cultured oral mucosal epithelium) for epithelialization of limbal stem cell deficiencies in ophthalmology were approved in 2020 and 2021, respectively. To develop regenerative medicine products, it is necessary to ensure the safety of raw materials, standardize the cultivation process, examine cell characteristics on GLP tests, construct transportation methods, build facilities, and conduct clinical trials.
