About the stem cell in-house lab (CPC)

The in-house lab (CPC) at Helene Clinic operates under the most stringent standards, adhering to rigorous environmental and hygiene control protocols. Inside the clean benches, a continuous supply of ISO Class 5 (Class 100) purified air ensures a completely sterile and contamination-free environment for cell processing.

To safely expand and manage cellular materials, Cell Processing Centers (CPCs) must adhere to exceptionally high standards that minimize microparticulates, creating a strictly sterile environment completely free of microbial contamination. Furthermore, to guarantee the absolute highest level of safety, comprehensive viral screenings and rigorous testing are routinely conducted immediately upon cell arrival.

Furthermore, to completely eliminate the risk of sample mix-ups, we utilize an advanced barcode-driven traceability system alongside a rigorous quality control framework that seamlessly monitors and logs the complete history of every single stage in the cell culture process.

Key Features of Helene Clinic In-house Lab (CPC)

Helene clinic features an on-site in-house lab (CPC), allowing us to seamlessly expand stem cells harvested from the patients and process them to the precise quantity, quality required for advanced treatments and pioneering research. At Omotesando Helene Clinic, we place a primary focus on mesenchymal stem cells (MSCs), optimizing customized culture mediums and environmental conditions based on specific cellular profiles to safely proliferate cells while meticulously preserving their undifferentiated state and functionality, thereby supplying premium-grade cells perfectly suited for clinical applications.

Inside the in-house lab (CPC), we thoroughly eliminate external microbial contamination through the strategic utilization of clean benches and advanced cleanrooms. Before entry, technicians must don sterile cleanroom suits, perform rigorous hand disinfection, and sanitize all equipment with medical-grade alcohol. Upon the completion of procedures, the environment undergoes UV irradiation sterilization to maintain a consistently pristine and optimal state. Furthermore, we have integrated our own stringent contamination risk reduction measures, such as the "shortest exposure principle" and a "two-stage cleaning" protocol, to seamlessly achieve the highest standards of both safety and quality.

Facilities & Equipment

Advanced Aseptic Processing & Optimized Cell Proliferation

Advanced Aseptic Processing & Optimized Cell Proliferation

Fully aligned with the strict standards for Specific Cell-Processed Products mandated by the Japanese Ministry of Health, Labour and Welfare (MHLW), every single step of our operation is conducted within a flawless sterile environment using advanced clean benches. We confidently guarantee absolute safety and premium quality by applying rigorous procedural protocols and meticulous record management to both routine culture medium changes and critical subculturing phases.

Cell Cultivation Under Strict Homeostatic Conditions

Cell Cultivation Under Strict Homeostatic Conditions

We achieve stable, high-fidelity cultivation by utilizing state-of-the-art incubators that flawlessly maintain optimal physiological conditions at 37°C, 5% CO₂, and over 90% humidity. To eliminate any risk of cross-contamination, our facilities feature built-in UV sterilization and advanced HEPA filtration, strictly operating under an uncompromised "one batch, one incubator" protocol.

Microscopic Observation and Cell Verification (Cell identification)

Microscopic Observation and Cell Verification (Cell identification)

We continuously evaluate the adhesion status, cellular morphology, proliferation rates, and any potential signs of contamination in our Mesenchymal Stem Cells (MSCs). Utilizing advanced inverted phase-contrast and fluorescence microscopy, our specialists precisely verify nuclear staining (such as DAPI) and specific surface marker expressions. By implementing standardized, highly detailed recording formats, we ensure the early detection of even the slightest cellular anomalies.
