Autologous adipose-derived stem cell therapy uses mesenchymal stem cells (MSCs) harvested from your own fat tissue. Because the cells come from your own body, there is virtually zero risk of immune rejection or allergic reaction. At CELL GRAND CLINIC in Osaka, Japan, we culture these cells at our pharmaceutical-grade Cell Processing Center — to reach 100–200 million high-viability cells per treatment. This far exceeds the minimal cell counts offered by same-day, non-cultured procedures available in many countries. Japan’s Act on the Safety of Regenerative Medicine ensures every treatment plan is registered with and approved by the Ministry of Health, Labour and Welfare (MHLW), providing a level of government-backed regulatory oversight that is unmatched globally.

Japan is the only country with a dedicated national law (the Act on the Safety of Regenerative Medicine, enacted 2014) specifically designed to regulate and promote regenerative medicine. CELL GRAND CLINIC holds 13 government-approved treatment protocols (Type 2 and Type 3) — one of the widest treatment scopes among regenerative medicine clinics in Japan. Our medical director, Dr. Yuichi Wakabayashi, is board-certified by the American Board of Regenerative Medicine, has published first-author research in leading international journals including the Journal of Nuclear Medicine and ACS Chemical Neuroscience, was a research fellow at the U.S. National Institutes of Health (NIH), and has been profiled in The Wall Street Journal for his innovative, patient-centered approach. Located in Osaka’s prestigious Shinsaibashi district, our international patients enjoy concierge-level medical care combined with Japan’s renowned hospitality, Michelin-starred cuisine, and world-class cultural experiences — all within easy reach of Kansai International Airport.

On your very first visit to CELL GRAND CLINIC, you can receive several premium treatments that do not require advance cell cultivation: (1) Stem Cell Culture Supernatant (Exosome) Therapy — harnessing growth factors and exosomes for immediate anti-aging, anti-inflammatory, and tissue repair benefits; (2) NMN (Nicotinamide Mononucleotide) IV Drip — a powerful NAD+ precursor that restores cellular energy and activates longevity genes; (3) PRP (Platelet-Rich Plasma) Therapy — for skin rejuvenation, hair restoration, or joint injection; (4) NK Cell Immunotherapy consultation and blood draw for cancer prevention; (5) Comprehensive Cancer Screening; and (6) Initial consultation with fat tissue harvesting (mini-liposuction under local anesthesia) to begin your stem cell cultivation process. These same-day options mean you start your regenerative journey immediately — even during a brief visit to Japan.

Yes — and we specifically design our protocols to maximize the medical value of every visit for international patients. On the day of your fat tissue harvesting (adipose aspiration), you can simultaneously receive: Stem Cell Culture Supernatant (Exosome) therapy  (IV and/or targeted injection) for an immediate regenerative boost; NMN IV therapy to enhance cellular energy; PRP injections for skin, scalp, or joints; comprehensive blood work and health screening; and a detailed treatment planning consultation with Dr. Wakabayashi. While your harvested stem cells are sent to our CPC for 7 weeks of pharmaceutical-grade cultivation, many of our international patients report feeling noticeably revitalized from the exosome and NMN therapy they received on day one. This approach ensures you leave Japan already experiencing tangible benefits while your personalized, high-potency stem cells are being prepared for your second visit.

Absolutely — personalized multi-visit treatment planning is one of our core specialties for international patients. A typical plan: Visit 1: Comprehensive consultation, medical evaluation, blood tests, adipose tissue harvesting, plus same-day treatments (exosome, NMN drip, PRP). Your cells begin cultivation at our CPC. Visit 2 (7 weeks later): Your first cultured stem cell infusion (IV and/or targeted injection). Surplus cells can be cryopreserved (frozen) for future use — eliminating the need for repeat fat harvesting. Visit 3 and beyond: Follow-up stem cell infusions using your banked frozen cells, combined with booster treatments such as exosome and NMN therapy. For patients with multiple treatment goals (e.g., knee osteoarthritis + anti-aging + hair restoration + skin rejuvenation), we design consolidated protocols that address all concerns during each visit. Our international patient coordinator communicates via WhatsApp and email between visits, monitoring your progress remotely.

CELL GRAND CLINIC administers 100 to 200 million cultured autologous adipose-derived stem cells per each treatment session, with a verified cell viability rate of 98% or higher. Cell count and viability are critical — peer-reviewed research consistently shows that higher doses of viable MSCs produce better clinical outcomes. Many clinics worldwide offer ‘same-day’ uncultured procedures yielding only 1–5 million stem cells with unpredictable quality. Our cells are cultivated at our CPC using third-passage (P3) protocols, which scientific evidence shows produce the optimal balance of cell potency, ideal cell size, and differentiation capacity. Critically, we never pre-batch or stockpile cells. Every treatment uses freshly cultivated cells prepared individually for each patient, with each batch independently tested for viability, sterility, mycoplasma, and endotoxin levels before administration.

CELL GRAND CLINIC holds 13 government-approved treatment protocols registered with Japan’s MHLW: Chronic Pain (PB5240089), Knee Osteoarthritis (PB5240090), Type 2 Diabetes and Prediabetes (PB5250050), Arteriosclerosis (PB5250051), Age-Related Frailty / Anti-Aging (PB5250049), AGA and FAGA (PB5250047), Erectile Dysfunction (PB5250048), PRP Intra-Articular for OA (PB5250010), Skin Aging (PB5250055), Skin Regeneration with Fibroblasts (PB5250028), PRP Skin Regeneration (PC5250008), PRP Hair Regeneration (PC5250007), and NK Cell Immunotherapy (PC5250041).

Japan has the world’s most comprehensive regulatory framework specifically for regenerative medicine. The Act on the Safety of Regenerative Medicine (2014) classifies treatments into three risk tiers (Type 1, 2, and 3) and requires every clinic to submit detailed treatment plans to the MHLW before offering any procedure. An independent Certified Special Committee reviews each plan for scientific validity and safety. CELL GRAND CLINIC’s 13 approved protocols have all passed this rigorous government review. Our cells are cultivated at a licensed CPC that meets pharmaceutical-grade GMP standards with full traceability. Dr. Wakabayashi personally oversees all treatments. International patients receive the same regulatory protections as Japanese citizens.

Treatment costs vary by condition and protocol. Stem cell therapy start from approximately USD $21,000 (100 million cell). All packages include: medical consultation with Dr. Wakabayashi (in English), adipose tissue harvesting, cell cultivation at our CPC, stem cell administration, and follow-up care. Our pricing is fully transparent. Contact us via WhatsApp or email (info@cellgrandclinic.com) for a personalized quote.

Three critical factors: (1) Pharmaceutical-grade external CPC operating under GMP-equivalent standards with independent quality oversight. (2) Optimized passage protocol: We use third-passage (P3) cultured cells for the ideal balance of potency, size, and differentiation capacity with ISCT protocol. (3) Individual preparation: Viability rate exceeds 98%, verified by independent batch testing. We never pre-batch or stockpile cells. Every treatment is freshly cultivated and tested for sterility, endotoxin, and mycoplasma before administration.

Yes. Popular packages include: ‘Total Regeneration’ — IV stem cell + exosome + NMN for anti-aging; ‘Knee + Mobility Recovery’ — intra-articular stem cell + PRP for knee OA; ‘Premium Aesthetic Regeneration’ — stem cells + autologous fibroblast therapy (dual-cell protocol) for wrinkles/sagging; ‘Complete Preventive Health’ — stem cell + NK Cell Immunotherapy + health screening; and ‘Men’s Vitality’ — stem cell for ED + anti-aging IV. Those combined treatment sometimes requires 2day visit. Dr. Wakabayashi designs customized multi-treatment plans for each patient.

Many patients report initial improvements in energy and sleep within 2–4 weeks. Knee OA: pain reduction within 1–3 months. Anti-aging: progressively evident over 3–6 months. Diabetes: blood glucose improvements within 2–4 months. The regenerative process continues for 6–12 months (tissue repair, angiogenesis, inflammation reduction). Benefits can last over years (it depends on severity), with maintenance infusions recommended every 12 months. We provide regular remote follow-up.

Minimally invasive. Fat harvesting: local anesthesia, 30 min, mild pressure only. IV infusion: 60 min, essentially painless. Joint injections: local anesthesia at injection site. No significant downtime — patients can sightsee in Osaka the same day. International patients routinely combine treatment visits with leisure travel, including Osaka’s food culture and Kyoto (30–45 min by train).

Yes. Surplus stem cells are cryopreserved (frozen) at our CPC for future use. This eliminates the need for repeat fat harvesting on subsequent visits. Simply schedule a brief visit to Osaka, and banked cells can be thawed and prepared.

vs. USA: Japan legally permits cell expansion, enabling 100–200M cells. Most U.S. clinics limited to same-day procedures (few million cells) due to FDA restrictions. vs. Southeast Asia: Less expensive but less stringent regulation. Japan has mandatory government registration and licensed CPCs. vs. Europe: Japan’s conditional approval pathway (2014) created the world’s most advanced commercial regenerative medicine infrastructure. CELL GRAND CLINIC combines American Board certification, pharmaceutical-grade CPC, published research, and Japan’s world-class healthcare system.

Yes. Diabetes, cardiovascular disease, chronic pain, osteoarthritis, and autoimmune conditions are our core treatment areas. Patients on insulin, antihypertensives, statins, or pain management can generally receive stem cell therapy with adjusted protocols. Main contraindications: active untreated malignant cancer and certain acute infections. Dr. Wakabayashi will review your complete medical history during pre-consultation to determine the safest approach.

Exosomes are nano-sized vesicles (30–150 nm) secreted by stem cells, carrying growth factors, cytokines, and microRNA. They deliver regenerative signals to surrounding tissues. At CELL GRAND CLINIC, we offer Stem Cell Culture Supernatant Therapy (rich in exosomes) as a standalone treatment and a complement to cultured stem cells. It can be administered same-day with no cultivation period. When combined with 100–200M cell treatment, exosomes provide an immediate boost while cultured cells drive deeper, long-term repair. Each IV delivers 300 billion exosomes.
