What Is the Transport of Regenerative Medicine Products?
Regenerative medicine products refer to pharmaceuticals and medical products manufactured by processing human or animal cells and tissues. These include cell therapy products such as CAR-T, NK cell therapies, and dendritic cell vaccines; gene therapy products; tissue-engineered products such as artificial skin, cartilage, and corneas; and stem cell-based products derived from iPS cells, ES cells, and MSCs. Because these products contain living cells, the quality of temperature control, time control, and handling during transport directly affects cell viability and product efficacy.
Why Is Transporting Regenerative Medicine Products Challenging?
Since cell viability is directly linked to product quality, temperature excursions, vibration, and transit delays can cause cell death, leaving extremely little margin for error. Transport requirements also vary significantly from product to product, and each product requires individual transport validation for conditions ranging from +2 to +8°C to as low as -196°C. In some cases, non-frozen cell products must be delivered and administered to the patient within only a few hours to a few days after manufacturing. For autologous products, such as CAR-T cell therapies manufactured from the patient’s own cells, product mix-ups are unacceptable, making strict chain-of-custody management essential.
Transport Methods by Temperature Range
For +2 to +8°C refrigerated transport, typical products include mesenchymal stem cell products, non-frozen cell suspensions, and tissue-engineered products. Passive refrigerated containers using PCM are used, and in many cases delivery must be completed within 72 hours.
For -80°C ultra-low temperature frozen transport, typical products include frozen biopharmaceuticals and certain CAR-T cell products. Passive containers using dry ice are commonly used. Because dry ice is classified as an IATA dangerous good (Class 9), dedicated declaration and packing procedures are required.
For -150 to -196°C liquid nitrogen cryogenic transport, typical products include CAR-T cells, NK cells, iPS cells, and stem cell products. Liquid nitrogen dry shippers operating in the vapor phase are used and can generally maintain temperatures below -150°C for up to around 10 days.
Regulatory Compliance in International Transport
For exports from Japan, if the product falls under the category of regenerative medicine products under the Pharmaceuticals and Medical Devices Act, confirmation of the product classification may be required during export customs clearance. Products containing human-derived cells or tissues may also require declaration as biologically derived materials.
For imports into Japan, products containing human- or animal-derived components may require quarantine procedures or confirmation applications. Unapproved investigational products used in clinical trials must also be consistent with the relevant clinical trial notifications.
THERMAL™ Support for Regenerative Medicine Product Transport
We support ultra-low temperature transport by arranging rental of MVE cryo shippers and similar equipment through our partners and performing pre-shipment conditioning. We also provide end-to-end support for dry ice shipments, including IATA dangerous goods documentation and handling for Class 9 materials. Our in-house customs team is experienced in the import and export of regenerative medicine products and biologically derived materials, and we continuously maintain WHO GDP certification.
Frequently Asked Questions
Q. Can you handle international transport of CAR-T cells?
A. Yes. Transport using liquid nitrogen cryo shippers at -150 to -196°C is the standard method. We also support patient identification control and chain-of-custody documentation for autologous products.
Q. Can I also request transport of research samples such as iPS cells and stem cells?A. Yes. We handle both domestic and international transport of research cell samples for universities and research institutions.
Q. Can liquid nitrogen cryo shippers be used for air transport?
A. Yes. Vapor-phase liquid nitrogen dry shippers are permitted under IATA regulations. However, some airlines or aircraft types may impose loading restrictions, so advance route-specific confirmation is required.
Q. Can I arrange transport of live research mice or rats together with regenerative medicine samples?
A. Yes. We can support both live transport of research animals such as rodents and the transport of biopharmaceuticals or research samples as part of the same project.
