Stem Cell & Bone Marrow Transport: Why Hand-Carry is the Only Option
In regenerative medicine, the margin for error is zero. Once stem cells or bone marrow have been collected from a donor, the clock starts immediately. Viability windows are narrow — in many cases between 24 and 72 hours — and every decision made in that window determines whether a patient receives a life-saving transplant or not.
At Cryo Medical Logistics, we exist for exactly this moment.
Specialists in Time-Critical Biological Transport
CML is a dedicated hand-carry cryogenic courier service, transporting stem cells, bone marrow, and advanced biologics across the UK, USA, Africa, and island destinations worldwide. We do not subcontract. We do not hand off. Every transport is managed end-to-end by our trained specialists, with full chain of custody from collection point to receiving clinic.
We understand that these are not parcels. They are a patient's only chance.
Temperature Is Everything
Not all biological materials travel the same way, and not all couriers understand the difference. CML manages transport across the full temperature spectrum required for stem cell and bone marrow logistics:
Cryogenic (-196°C): For frozen stem cell products, embryos, and long-term preserved biologics transported in liquid nitrogen dry shippers. Temperature is maintained throughout the entire journey — no exceptions, no breaks in the cold chain.
Refrigerated (2–8°C): For fresh bone marrow, peripheral blood stem cells, and certain cellular therapies that must remain chilled but cannot be frozen. Precision monitoring throughout.
Ambient (15–25°C): For specific biological samples and supporting materials that require controlled room temperature rather than refrigeration.
Understanding which product requires which temperature — and never confusing the two — is not a detail. It is the mission.
What Sets CML Apart
Hand-carry only. Your biological material travels with a dedicated CML courier as cabin baggage. It never enters cargo holds, never passes through automated freight systems, and is never exposed to airport X-ray screening.
24/7 availability. Stem cell collections don't happen on schedule. Neither do we. CML is available around the clock for emergency mobilisation, route planning, and in-transit support.
Full documentation. Every transport is accompanied by complete chain of custody records, temperature logs, and regulatory documentation tailored to the destination country.
Global reach. We collect from laboratories, hospitals, and donor centres across the UK, United States, Africa, and island territories, and we deliver to transplant centres worldwide.
Regulatory expertise. International biological transport is complex. Import permits, customs clearance, IATA compliance — CML navigates the regulatory landscape so clinics and patients don't have to.
Bridging Donor to Patient Across Continents
Whether a stem cell donation originates in London and is destined for Lagos, or collected in Houston and bound for a transplant centre in Barbados, CML provides the same standard of care: supervised, temperature-controlled, fully documented hand-carry transport with no compromise on integrity.
We work with stem cell laboratories, bone marrow registries, fertility clinics, hospitals, and research institutions who need a logistics partner that treats every transport as the life-critical mission it is.

Frequently Asked Questions: Stem Cell & Bone Marrow Transport
Q: How long do stem cells remain viable during transport?
A: Fresh stem cells and bone marrow have a critical 72-hour window from collection to transplant. During this period, temperature control is non-negotiable—even minor fluctuations compromise viability. If cells are cryopreserved before transport, they can remain viable for years when stored at minus 196 degrees Celsius. CML maintains this temperature throughout every journey using certified dry shippers, ensuring zero degradation.
Q: What's the difference between cryogenic, refrigerated, and ambient transport?
A: Different stem cell products require different temperatures. Cryogenic transport at minus 196 degrees Celsius is for frozen stem cell products and long-term preserved biologics. Refrigerated transport at two to eight degrees Celsius is for fresh bone marrow and peripheral blood stem cells that must remain chilled but cannot be frozen. Ambient transport at 15 to 25 degrees Celsius is for certain biological materials and supporting documentation. CML manages the full spectrum and never confuses the protocols.
Q: Why can't standard couriers like FedEx or DHL transport stem cells?
A: Commercial couriers are not equipped for biological time-criticality. Standard logistics involve cargo holds, automated sorting systems, X-ray screening, and temperature fluctuations—all of which damage stem cell viability. CML uses hand-carry as cabin baggage only, bypassing cargo systems and maintaining continuous temperature control with a dedicated courier present throughout the journey.
Q: Does airport X-ray screening damage stem cells?
A: Yes. X-ray exposure can harm stem cell integrity. WMDA guidelines recommend avoiding X-ray screening where possible. CML works proactively with airlines and customs to ensure our hand-carry shipments bypass standard security X-ray screening, protecting the biological material throughout transport.
Q: How does CML maintain temperature control during international flights?
A: We use certified dry shippers filled with liquid nitrogen that maintain minus 196 degrees Celsius for the entire journey. These are packed to airline specifications, carried as cabin baggage by our trained courier, and monitored continuously. Temperature data is logged and documented for full chain of custody accountability.
Q: What documentation does CML provide for international stem cell transport?
A: Every CML transport includes complete chain of custody records, real-time temperature logs, IATA compliance documentation, import permits for the destination country, and customs clearance support. This ensures regulatory compliance and legal protection across all jurisdictions.
Q: Can stem cells be transported across borders?
A: Yes, but international transport requires careful regulatory navigation. Import permits, customs clearance, and country-specific regulations vary by destination. CML has expertise in moving stem cells between the UK, USA, Africa, and island territories, managing all regulatory requirements so your institution doesn't have to.
Q: How quickly can CML mobilise for an urgent stem cell transport?
A: CML operates 24 hours a day, seven days a week. Once a collection is confirmed, we can dispatch a courier within hours to ensure your stem cell product reaches the transplant centre on time. There is no weekend or holiday delay.
Q: What happens if there's a transport delay?
A: CML maintains continuous communication with clients throughout every journey. If any delay occurs, we notify the receiving centre immediately and adjust routing to minimise impact. Our hand-carry model eliminates most delay risks since we avoid freight systems, customs backlogs, and automated sorting queues.
Q: How does CML differ from other stem cell transport providers?
A: CML is a dedicated hand-carry specialist with no subcontracting. Every transport is managed end-to-end by our trained personnel. We maintain minus 196 degrees Celsius throughout, offer 24/7 availability, provide full regulatory expertise, and have established routes across the UK, USA, Africa, and island territories. Your cells never leave our custody.
