CellSource and C-FORTE Launch Business Partnership in Regenerative Medicine x Rehabilitation

CellSource Co., Ltd. (Representative Director and CEO: Masayuki Yamakawa; hereinafter 'CellSource') and medical consulting firm C-FORTE Co., Ltd. (Representative Director: Kei Noguchi; hereinafter 'C-FORTE') are pleased to announce the start of a business alliance aimed at building a new medical delivery model in the fields of regenerative medicine and rehabilitation.

▪ Background and Purpose of the Partnership While regenerative medicine has been expanding in the orthopedic field in recent years, its efficacy and widespread adoption have not been fully realized in clinical settings due to challenges such as: - Lack of coordination with rehabilitation - Insufficient know-how to introduce out-of-pocket (uninsured) medical treatments - Poorly designed patient touchpoints Furthermore, under the current medical system centered on insurance-covered treatments, there are limits to the value that both medical institutions and physical therapists can provide due to medical fee restrictions. To address these issues, this partnership will promote: - Construction of a treatment model integrating regenerative medicine and rehabilitation - Establishment of a system to support the introduction of out-of-pocket treatments - Creation of patient touchpoints centered on physical therapists By doing so, we aim to maximize the effectiveness of regenerative medicine and accelerate its social implementation.

▪ Overview of the Partnership In this partnership, we will work on building a unified mechanism of 'Human Resources, Systems, and Operations' to promote regenerative medicine. 1. Organization of Physical Therapists and Establishment of a Certification System We will organize physical therapists and provide an environment where they can systematically acquire specialized knowledge and practical skills in regenerative medicine. Simultaneously, we will introduce a certification system for those who reach a certain level, creating new career paths and advancing their expertise. 2. Establishment of an Association and Educational Infrastructure We will support the founding of an association blending regenerative medicine and rehabilitation, operate educational curricula and study groups for doctors and physical therapists, and provide continuous educational and certification programs. 3. Support for Building Operations for Medical Institutions We will design a clinical model combining regenerative medicine and rehabilitation and support the construction of operations for introducing out-of-pocket treatments. 4. Promotion of Educational and Enlightenment Activities We will conduct outreach activities for medical institutions through seminars and webinars, and provide introduction and retention support for onsite staff.

▪ Significance of the Partnership This initiative aims to build a new healthcare ecosystem that offers: - For medical institutions: Expanded treatment options and enhanced medical delivery systems - For physical therapists: Establishment of new roles and careers - For patients: Improved access to higher quality treatments Furthermore, by properly popularizing out-of-pocket treatments, we aim to supplement diverse medical needs and contribute to realizing a sustainable medical delivery system.

▪ Roles of Each Company CellSource: Responsible for providing medical technology and research data, utilizing its expert network, and supporting the spread to medical institutions. C-FORTE: Responsible for operating the association, constructing the educational curriculum and certification system, consulting for medical institutions, and supporting onsite implementation.

▪ Future Outlook Through this partnership, both companies will promote the project in phases starting in April 2026, expanding to medical institutions nationwide. Ultimately, we aim to establish a regenerative medicine delivery system that leverages the expertise of physical therapists, making regenerative medicine more accessible and effective in society.

CellSource will continue to promote the social implementation of regenerative medicine and strive to create new value in healthcare.
