From donated cord tissue to a treatment-ready dose: the laboratory journey that determines whether your stem cells are worth paying for.
The single biggest factor in the quality of your stem cell treatment is something you will never see: the laboratory that prepared the cells. Here is what happens inside a well-run facility, and why it matters for your outcome.
The journey from tissue to treatment
- Donation and screening. Umbilical cord tissue is collected after healthy births with informed consent. Donors are screened for infectious diseases and medical history.
- Isolation. Technicians extract MSCs from the cord tissue and establish a starter culture.
- Expansion. The cells multiply in controlled incubators over several passages until the target quantity is reached.
- Quality control. Samples are tested for sterility, mycoplasma, endotoxin, identity markers and potency.
- Formulation and release. The final dose is counted, checked for viability, documented in a certificate of analysis, and released for clinical use — fresh or cryopreserved.
What GMP actually guarantees
GMP — Good Manufacturing Practice — means the laboratory operates validated processes in controlled clean-room environments, with every step documented and traceable. For you as a patient, GMP translates into three practical assurances: the cells are what the label says, they are free of contamination, and the dose is measured rather than estimated.
Signs of a strong laboratory operation
- Named laboratory with stated certifications (GMP, ISO, or national equivalents)
- Batch-specific certificates of analysis issued as standard
- Published cell counts and viability figures
- Clear cold-chain or fresh-delivery logistics
- Staff who can explain the process when you ask
A clinic's answer to 'where do your cells come from?' tells you almost everything about its standards.
Several Thai clinics operate their own laboratories and publish their documentation — you can compare them in our clinic directory. To understand the paperwork a laboratory should give you, read how to read a COA.
Frequently asked questions
What does GMP mean?
Good Manufacturing Practice — an international quality standard for producing medicinal products. A GMP laboratory follows validated processes, controlled environments and documented testing at every step.
Does the clinic treat me with cells from its own laboratory?
Some Thai clinics operate their own processing laboratories; others source from specialist GMP facilities. Both models can deliver excellent quality — what matters is documentation and testing, which you can request either way.
What tests are performed before cells are released?
Standard release testing includes sterility (bacterial and fungal), mycoplasma, endotoxin, cell count, viability, and identity markers confirming the cells are genuine MSCs.
How can I verify a clinic's laboratory standards?
Ask which laboratory produces the cells, what certifications it holds, and request the certificate of analysis for your batch. Quality clinics welcome these questions.
