Cell Grand Clinic is a regenerative medicine center based in Osaka, Japan, specializing in autologous stem cell therapy and advanced longevity treatments for international patients.
Cell Grand Clinic operates within one of the most advanced regulatory environments for regenerative medicine in the world — Japan. Under the Act on the Safety of Regenerative Medicine, all treatments follow strict government oversight, ensuring safety, traceability, and standardized protocols.
Cell Grand Clinic focus on autologous stem cell therapy and advanced regenerative treatments designed to support recovery, improve function, and enhance long-term health outcomes.
Led by Dr. Yuichi Wakabayashi, an internationally trained physician and researcher, the clinic applies a science-driven approach to cellular therapy — using each patient’s own biological material to promote repair, reduce inflammation, and restore physiological balance.
Rather than offering generalized treatments, Cell Grand Clinic develops personalized protocols based on each patient’s condition, goals, and medical profile, making it a strong option for patients seeking advanced care beyond conventional medicine.
Each treatment follows a controlled process that includes cell extraction, laboratory expansion in a certified facility, and precise administration. The clinic emphasizes cell quality, viability, and individualized treatment planning rather than high-volume procedures.
Cell Grand Clinic is a regenerative medicine clinic in Osaka, Japan specializing in autologous stem cell therapy, longevity treatments, and advanced cellular therapies designed to support tissue repair, reduce inflammation, and improve overall physiological function.
The clinic operates under Japan’s Act on the Safety of Regenerative Medicine, one of the most advanced regulatory frameworks in the world for stem cell therapy. Under this system, all treatment protocols must be reviewed and approved by independent certified committees, and outcomes are continuously monitored and reported at a national level.
Unlike many international clinics that operate with limited oversight, Cell Grand Clinic follows a structured, government-regulated model that emphasizes safety, traceability, and treatment standardization.
All therapies are based on autologous adipose-derived stem cells, meaning cells are collected from the patient’s own body and expanded in a certified Cell Processing Center (CPC) under pharmaceutical-grade conditions. Each batch undergoes strict quality control, including testing for viability, purity, and sterility before administration.
The clinic’s approach is not focused on replacing conventional medicine, but on supporting the body’s natural repair mechanisms through targeted cellular therapy. Treatments are designed to address underlying biological processes such as inflammation, tissue degeneration, and reduced cellular function.

Travel Tips:
As a type 2 diabetes patient, I have struggled for years with the side effects of medication and have been searching for a more long-term solution. After speaking with my doctor, I learned about stem cell therapy as a possible option that could help address the condition more fundamentally. I was not comfortable with treatments using animal-derived or donor stem cells, so I spent a lot of time researching different options. In the end, I decided to undergo self-derived stem cell therapy in Japan, which felt much safer and more reassuring to me. Before traveling to Japan, I had an online consultation with Dr. Wakabayashi. He was very kind and patient, and he took the time to clearly explain the treatment process and what I could realistically expect, which gave me a lot of confidence. I traveled all the way from the United States to Japan, and although the journey was long, I was very happy to finally meet Dr. Wakabayashi in person. This month, he personally performed the fat tissue collection procedure for me. Everything went very smoothly, and his skill and attention to detail were truly impressive. I felt well cared for throughout the entire experience. I am now waiting for my stem cell treatment in two months and feel very hopeful about the results. I am grateful for the professionalism, high safety standards, and attentive care provided by this clinic, and I would highly recommend it to anyone considering stem cell therapy.
I visited Selgrand Clinic, located above FENDI on Midosuji Street in Osaka. The clinic was very clean, with a luxurious and calming atmosphere, allowing me to receive treatment with peace of mind. The consultation was thorough, and I got the impression that they listened closely to my concerns and made the best possible suggestions. They didn't try to sell me anything, so I felt it was a trustworthy clinic. I was very satisfied with the changes after the treatment, and it's a place I'd like to continue visiting in the future.

I’ve been struggling with shoulder and knee pain for a while, and nothing seemed to work. A friend recommended Cell Grand Clinic, so I decided to give it a try. The clinic has a very clean and welcoming atmosphere, and the staff were friendly and professional. I tried the exosome infusion for the first time, and the whole process was relaxing and painless. Surprisingly, even after just one treatment, I felt like the tension in my shoulder and knee had slightly eased the next day. I understand results can vary from person to person, but I was happy to notice even a small improvement. I’ll keep monitoring how things progress and might share an update if I notice more changes.
I was suffering from chronic pain, especially the severe shoulder pain and pain from a herniated disc in my lower back, which was interfering with my daily life. I received stem cell therapy infusions here, and I was surprised at how much better my body felt than I expected. The doctor is a specialist and very knowledgeable, and he gave a thorough initial explanation and answered all of my concerns and questions in an easy-to-understand manner. I didn't feel pressured into receiving treatment, and he clearly explained the advantages and disadvantages of the treatment, so I felt at ease. The clinic is clean, and the staff are very calm and welcoming. If you're suffering from chronic pain, I recommend consulting him.
慢性的な痛みで悩んでいて、特に肩の痛みと腰のヘルニアの痛みがつらく、日常生活にも支障が出ていました。こちらで幹細胞治療の点滴を受けましたが、想像以上に体が楽になって驚いています。 先生が専門医で知識が深く、最初の説明も丁寧で、こちらの不安や質問にも一つ一つわかりやすく答えてくれました。無理に勧められる感じもなく、治療のメリット・デメリットをきちんと説明してくれたので安心して受けられました。 院内も清潔感があり、スタッフさんの対応も落ち着いていて良かったです。慢性痛で悩んでいる方は一度相談してみてもいいと思います。
The exosome and NMN drips were fantastic. I really appreciated the attention to quality control — it's something Japan truly excels at. They also showed me some before-and-after photos of facial exosome treatments, which made me want to try it for my face next time. I went with two friends, and the staff were warm and welcoming the entire time.
