What Is a CPC? Inside Japan’s Stem Cell Safety System

Take a guided look inside Japan’s certified Cell Processing Centers (CPCs) and learn how they keep stem cell therapies sterile, viable, and consistent.

Краткий ответ

Japan requires stem cells to be processed in licensed CPC facilities that maintain sterility, viability, and controlled culture conditions. Rakan Clinic operates its own in-house CPC within Azabudai Hills.

A Cell Processing Center (CPC) is the nerve centre of any legitimate stem cell programme. Japan’s regulations demand CPC licensing, routine inspections, and traceable documentation for every batch of cells.

CPC = Cell Processing Center Explained

CPCs are clean-room laboratories with filtered air, pressure controls, and validated equipment. They follow Good Manufacturing Practice principles to guarantee purity and consistency.

In-House Culture Maintains Cell Freshness

By keeping our CPC on-site, we eliminate transport delays. Cells are collected, expanded, tested, and reinfused without leaving the building—protecting viability and reducing contamination risk.

Use of the Patient’s Own Blood for Safety

We supplement stem cell cultures with autologous serum instead of animal-derived media. This approach minimises allergy risks and aligns with PMDA guidance on personalised therapies.

Zero Transport Contamination Risk

  • Cells move through protected corridors under monitored temperature and humidity.
  • Release testing confirms sterility, endotoxin levels, and cell counts before infusion.
  • Digital logs capture every touchpoint for complete traceability.

Частые вопросы

What happens inside a CPC?

Cells are isolated, expanded, washed, and tested within ISO-class clean rooms using validated protocols and constant environmental monitoring.

How long do stem cell therapy results last?

High-quality CPC processing contributes to durable outcomes—typically 12–36 months—because viable cells engraft more effectively.

Does CPC processing add discomfort?

No. CPC work happens behind the scenes. Patients relax in private suites while our laboratory team prepares the infusion.

How many sessions will I need?

We tailor session frequency to your diagnosis. Many patients repeat therapy every four months to maintain progress.
