Stem cell therapy represents one of the most promising frontiers in modern regenerative medicine. At its core, stem cell therapy involves using the body's own master cells to repair, regenerate, and restore damaged tissues and organs.
Stem cells are unique cells with two remarkable properties: they can divide and create more stem cells (self-renewal), and they can differentiate into specialized cell types such as muscle cells, nerve cells, or cartilage cells. This versatility makes them incredibly powerful tools for healing.
At Rakan Clinic Tokyo, we specialize in autologous adipose-derived stem cell therapy. This means we harvest stem cells from your own fat tissue, process them in our state-of-the-art Cell Processing Center (CPC), and then reintroduce them to target areas where healing is needed.
The process begins with a minimally invasive fat collection procedure. A small amount of adipose tissue (fat) is extracted, typically from the abdomen or thigh area. This tissue is rich in mesenchymal stem cells (MSCs), which are particularly effective for orthopedic and regenerative applications.
These stem cells are then cultured and expanded in our in-house CPC under strict quality control protocols. The culture period typically lasts 6-8 weeks, during which the cells multiply while maintaining their regenerative potential.
Once the stem cells are ready, they are administered via intravenous infusion or direct injection into the affected area. The stem cells then work to reduce inflammation, promote tissue regeneration, and stimulate the body's natural healing processes.
Stem cell therapy has shown remarkable results in treating conditions such as osteoarthritis, sports injuries, chronic joint pain, and degenerative disc disease. Unlike traditional treatments that merely manage symptoms, stem cell therapy addresses the underlying cause by promoting actual tissue repair.
Why is Japan a Global Leader in Stem Cell Therapy?
Japan has established itself as a world leader in regenerative medicine through several key factors:
- Strict National Regulations: Japan's Act on Regenerative Medicine ensures rigorous oversight of stem cell processing and administration. All facilities must comply with PMDA (Pharmaceuticals and Medical Devices Agency) standards.
- Certified CPC Facilities: Cell Processing Centers (CPCs) in Japan, including our facility at Rakan Clinic Tokyo, operate under strict certification requirements ensuring high cell viability, sterility, and quality control.
- Academic Excellence: Strong partnerships with leading institutions like the University of Tokyo provide ongoing research validation and clinical expertise.
- Safe Autologous Protocols: Japan emphasizes autologous (self-derived) stem cell therapy, eliminating donor cell risks and rejection concerns.
- Advanced MSC Culture Technology: Japanese facilities utilize cutting-edge mesenchymal stem cell (MSC) culture techniques that maximize therapeutic potential while maintaining safety standards.
At Rakan Clinic Tokyo, located in the prestigious Azabudai Hills medical district, we combine these national advantages with our state-of-the-art CPC to deliver world-class regenerative medicine.
Frequently Asked Questions
Is stem cell therapy safe?
Autologous stem cell therapy (using your own cells) has a strong safety record with low complication risk. At Rakan Clinic Tokyo, all procedures are performed in our certified CPC facility following Japan's strict regenerative medicine regulations.
What is a CPC (Cell Processing Center)?
A CPC is a certified facility where stem cells are processed, cultured, and prepared for treatment. Our CPC at Rakan Clinic Tokyo meets Japan's PMDA standards for sterility, quality control, and cell viability.
How long does the stem cell culture process take?
The culture period typically lasts 6-8 weeks. During this time, your stem cells are expanded in our CPC under strict quality control protocols to ensure optimal therapeutic potential.
Is stem cell therapy approved in Japan?
Yes. Japan has a comprehensive regulatory framework for regenerative medicine under the Act on Regenerative Medicine. All treatments at Rakan Clinic Tokyo comply with PMDA regulations and CPC certification requirements.
How long does stem cell therapy last?
Many patients experience benefits for 12–36 months, especially when they follow recommended booster schedules and rehabilitation plans.
Does the procedure hurt?
Fat collection may cause mild soreness for a day or two. Infusions themselves are typically painless and performed in a comfortable lounge.
How many sessions will I need?
We usually begin with one session and personalise booster frequency—often every four months—based on your goals and progress.
