Business purposeDevelopment of next generation regenerative medicine innovation using stem cells


Developing the next generative medicine using tissue stem cells and creating a platform where many young, promising and entrepreneurial scientists can unlock the full potential of stem cells

NextGeM Inc. has been established with the aim of providing the ultimate curative treatment method with limited side effects, focusing on the capacity of tissue stem cells , and making full use of their potential.

Adverse reactions tend to be significant especially when doctors provide treatment that has high curative effect. In other words, the best treatment policy for the doctors may not necessarily be the best option for their patients.

In order to reduce the gap between the two, NextGeM Inc is trying to develop next generation medical platform which can bring out the best therapeutic effect without affecting the patient's quality of life (QOL), which will help more patient to get high quality, less side effects and safe regenerative medical cure.

In the modern world, where social and industrial structures are being rapidly globalized, technological innovations are transforming our institutional, social and cultural norms, disrupting the conventional industrial fields faster than expected. Therefore, we believe that it is important to maximize the use of these state-of-the-art technologies and create new values.

Creating new values in this way is the most sought-after skill in Japan today, including in the scientific research world. In order to make full use of cutting edge technologies and to survive the upcoming fierce global competition, establishing a new platform involving a wide range of stakeholders across industry, academia, government and borders, seems to be of a great importance.

On the other hand, working environment for young scientists full of new, innovative and bold ideas tends to be extremely severe. Our secondary but important mission is to prepare an exciting, risk-tolerant and thrill-seeking platform where young and entrepreneurial scientists can realize their full potential, and to generate a role model for their career development.
