CELL GRAND CLINIC

Cell Grand Clinic is a private regenerative medicine practice in Osaka, Japan. Dr. Yuichi Wakabayashi founded it in 2006. The facility focuses on science-based, personalized regenerative solutions. It operates in the Nishishinsaibashi district, providing specialized outpatient care in a modern urban setting.

Accreditations and Achievements

The clinic operates under Japan's Act on the Safety of Regenerative Medicine (ASRM). This framework requires the Ministry of Health, Labour and Welfare (MHLW) to review all treatment plans. The clinic holds 13 accepted MHLW provision plans, so every protocol meets national safety standards.

In 2026, Healthcare Business Review APAC recognized the facility as a Top Regenerative Medicine Solution in APAC. All cell handling occurs in government-licensed Cell Processing Centers (License: FA5250001). This licensing means manufacturing conditions meet strict pharmaceutical-grade standards for patient safety.

Quality control follows global standards set by the International Society for Cell & Gene Therapy (ISCT). Specialists use ISCT-standard surface marker testing to verify cell identity before administration. Each patient receives a Certificate of Quality. It documents batch-specific purity, potency, and safety results.

Regenerative Medicine Specialties

The practice specializes in autologous adipose-derived stem cell (ADSC) therapy. This method uses a patient's own fat tissue to harvest regenerative cells. Dr. Yuichi Wakabayashi has personally performed over 3,000 stem cell procedures throughout his career.

Specialists treat various conditions using these regenerative techniques:

• Knee osteoarthritis and chronic joint pain – helping patients avoid surgery
• Metabolic disorders including diabetes mellitus and prediabetes
• Vascular health issues such as arteriosclerosis
• Anti-aging and longevity protocols for frailty and menopausal disorders
• Men's health concerns including erectile dysfunction and hair loss

The "Grand Stem Cell" program uses a structured cultivation process lasting about seven weeks. Cells are expanded to 100–200 million before infusion, depending on the protocol. The clinic only uses cells up to Passage 3 and keeps viability above 95% to preserve regenerative potency.

Additional options include stem cell culture supernatant (exosome) therapy and PRP. The clinic also offers fibroblast transplants for skin rejuvenation. These treatments can be combined in a single visit to address multiple health goals at once.

Advanced Protocols and Laboratory Standards

Cultivation protocols are developed through academic collaboration with Prof. Takahiro Ochiya of Tokyo Medical University. This partnership brings exosome biology and microRNA signaling research into clinical practice. The laboratory team conducts multi-marker purity testing on every cell batch.

Safety protocols include rigorous testing for contaminants before any administration. Specialists screen every batch for sterility, endotoxins, and mycoplasma. The clinic maintains end-to-end traceability, logging every step from fat tissue collection to final cell delivery.

International Patient Services

Dr. Yuichi Wakabayashi personally conducts consultations for international patients in English. He is a PhD-qualified physician who completed research training at the U.S. National Institutes of Health (NIH). The clinic provides bilingual support in English and Japanese for clear communication throughout.

The treatment journey for international patients follows three steps:

1. Remote pre-consultation for medical record review and eligibility assessment
2. An initial visit to Osaka for physical assessment and fat tissue harvesting
3. A second visit about seven weeks later for the cell infusion

Post-treatment care includes 6 and 12-month remote follow-up sessions. These check-ins let Dr. Wakabayashi monitor recovery and long-term outcomes after the patient returns home.
