Cell Processing Center (CPC)
Our in-house CPC ensures maximum cell freshness, safety, and treatment effectiveness through pharmaceutical-grade sterile processing.
Introduction
To maximize the effectiveness of stem cell treatment, our clinic has established a Cell Processing Center (CPC) within our medical facility.
We are committed to delivering highly fresh and high-quality stem cells to patients in the best possible condition.
What is CPC?
CPC (Cell Processing Center: 細胞培養加工室) is a specialized facility for processing and culturing cells used in regenerative medicine and cell therapy, ensuring a sterile and clean environment.
Managed under strict standards equivalent to pharmaceutical manufacturing
High cleanliness due to cleanroom structure
24-hour quality control system by dedicated culture specialists
Quality Appeal of Stem Cells
Our self-fat-derived stem cells maintain a survival rate of over 95%. Under a microscope, they appear healthy, uniform, and spindle-shaped — a crucial sign of their good condition.
Maintaining a uniform and beautiful form
Retaining proliferative capacity and differentiation potential
Being delivered in a fresh state at the time of administration
Directly contributing to the stability and safety of clinical effects
Latest Equipment to Protect Stem Cells
Biological Safety Cabinet
A device for aseptic operations. It protects cells and specimens aseptically, while also protecting operators and the environment from biohazards. It ensures a thoroughly clean space with HEPA filters and UV sterilization.
CO2 Incubator
Constantly maintains the temperature, humidity, and CO2 concentration essential for stem cell culture. Enables stable proliferation of cells in an optimal environment.
Inverted Microscope
A microscope that allows observation of living cells directly in their culture vessels. It continuously confirms cell morphology and growth processes, always grasping their healthy state.
Pass Box
A system used for transferring items between clean rooms or sterile rooms and the outside environment. With an interlock function that prevents both doors from opening simultaneously, thereby maintaining constant cleanliness and airtightness.
Centrifuge
Essential for cell separation and processing. Ensures precise handling of cell samples with controlled centrifugal force for optimal cell quality and viability.
Quality Management and Safety
High Cell Survival Rate (95% or more)
Cultivation starts immediately after fat collection to minimize damage.
Long-term Preservation with Liquid Nitrogen (-196°C)
Preserved in a semi-permanently usable state, can be administered at the necessary timing.
Administered in a Highly Fresh State
After cultivation, it is quickly administered intravenously to maximize regenerative power.
Passage Limit (up to 4 times)
Prevents aging and risks due to excessive cell division, ensuring safety.
Culture Specialists Permanently Stationed at CPC
Experienced cultivation specialists constantly monitor and manage cells, protecting quality.
We are thoroughly committed to the "quality" and "safety" of stem cell treatment. Our in-house CPC and state-of-the-art equipment, along with a management system by experienced cultivation specialists.
All of these form the foundation for patients to receive treatment with peace of mind. We will continue to deliver the highest standard of stem cell treatment.
Facility FAQs
A CPC is a certified, pharmaceutical-grade cleanroom facility where stem cells are isolated from adipose tissue, cultured, expanded, and prepared for therapeutic use. Our in-house CPC at Rakan Clinic Tokyo operates under strict sterility, temperature, and quality control protocols mandated by Japan's PMDA.
An in-house CPC gives us complete control over every step of the cell processing pipeline. This means higher cell viability, faster turnaround, and full traceability—from harvest to injection. Clinics that outsource cell processing to third-party labs have less control over quality and timing.
Our CPC is equipped with a Class II Biological Safety Cabinet for sterile handling, a CO2 incubator for precise cell culture conditions, an inverted microscope for real-time cell monitoring, a pass box system to maintain cleanroom integrity, and a centrifuge for cell separation and concentration.
We perform quality checks at every stage: cell count and viability testing after isolation, sterility testing during culture, and final potency verification before administration. Every batch is documented and traceable. Our protocols meet or exceed PMDA certification requirements.
Yes. Our CPC and clinical operations comply with all requirements under Japan's Act on Regenerative Medicine and PMDA standards. All treatment plans are registered with the Ministry of Health, Labour and Welfare (MHLW). We maintain full regulatory compliance at all times.
We are located in Azabudai Hills, one of Tokyo's newest and most prestigious mixed-use developments. The clinic is a 5-minute walk from Kamiyacho Station on the Tokyo Metro Hibiya Line. Azabudai Hills offers a world-class environment with restaurants, hotels, and wellness facilities surrounding the clinic.
