Are Cell Storage (Stem Cell Banking) Services Reliable? A 2026 Guide to Checking Cell Storage Services
JRQ consumer verification guide Published: November 6, 2026
The short answer: judging whether a cell storage (cell banking) service is reliable does not depend on how good the brochure looks. It depends on a few checkable things: where the facility is, how temperature is managed, how records are kept, and what the contract says. JRQ does not evaluate any service provider and does not answer whether stored cells will be useful later. This guide covers only one thing: how to verify before signing a contract.
Ask for the name and address of the storage facility first
Cells are stored for many years, so where they are kept is the most basic information. If a provider cannot clearly give the name and address, stop and ask until it is clear.
Check whether the provider states the name of the storage facility or only a company name. A company may collect cells but store them somewhere else. The storage facility should have its own name and a specific location, at least down to an identifiable building. Ask: “Which facility and which address will my cells be stored at?” If the provider can write this down immediately, that is the minimum baseline. Be wary if the address is vague, only gives a city, or says something like “a partner facility in Japan” without naming it.
This information should also match the contract. If the contract names facility A and the promotional materials name facility B, that alone is a problem.
Ask about storage temperature, transport handover, and record keeping together
Cell storage is not just “put it in the freezer and done.” From collection to intake, and for years afterward, several points can go wrong. Check them one by one.
How storage temperature is monitored and recorded. Under JRQ’s JRQ-P-007 Storage Temperature Control Standard, for cell storage that requires temperature control, focus on three things: what temperature the cells are kept at, whether temperature data is recorded continuously, and whether there is an alarm and response procedure for abnormal conditions. Ask about the records themselves: are they logged automatically by a machine or copied manually, how long are they kept, and can you see temperature data for the period your cells were stored? Saying “our temperature has always been fine” is not a record.
How alarms are handled. If equipment fails, the power goes out, or temperature becomes abnormal when no one is on site, how does the provider find out and respond? Ask for the specific procedure: who receives the alarm, how long response takes, and what the backup plan is if the problem cannot be fixed. If there is no alarm system, or they only say “a dedicated person is responsible” without describing the procedure, treat it as no system.
Is there a handover record for transport? Cells have to be transported from the collection site to the storage facility. Under JRQ’s JRQ-P-008 Transport and Transfer Standard, ask who performs the transport, whether temperature is controlled in transit, what container is used, and whether there is a handover record on arrival. The handover record should include at least the time, the parties involved, and the condition of the material. The collection site, the transporter, and the storage facility are three separate links; do not let them blur together.
Record keeping and traceability. Under JRQ’s JRQ-P-009 Record Retention Standard and JRQ-P-029 Traceability Standard, from receiving cells through intake, storage, and later retrieval, the whole process should be able to identify which sample it is, who handled it, and what records exist. Ask whether your cells have a unique identification number, how long records are kept, and whether records can be transferred if the facility or provider changes. If the history of your cells cannot be found, you have nothing to check against if you later retrieve them or use them for treatment.
Check five parts of the contract line by line
Promotional materials and the contract are different things. Before signing, find these five places in the contract. If any are unclear, ask the provider to add a written explanation.
| Contract item | What to check |
|---|---|
| Storage period | How the start and end dates are calculated, what happens when the period ends, and whether it renews automatically |
| Fee changes | Whether fees can change during the storage period, under what conditions, and how you will be notified |
| Business closure or transfer | If the operator stops doing business or transfers the business to someone else, what happens to the cells and who bears responsibility |
| Retrieval procedure | What procedure is needed to retrieve the cells, who pays the cost, and how the condition of the cells is confirmed at retrieval |
| Procedure for use in treatment | What materials are needed to hand the cells to a medical institution later, and who handles contact |
Among these, pay particular attention to the clause on business closure or transfer. Cell storage is long-term, so what happens if the provider closes or transfers the business must be agreed in the contract in advance. If the contract does not state it, or says something like “to be negotiated by both parties at that time,” treat it as not written.
Be wary of these claims in promotional materials
If you see claims like “storing cells can cure disease X in the future,” “store now and they can be used for any disease later,” or “storing cells is storing health,” do not treat them as a basis for signing. Whether cells can be used in the future, and for what, is a medical judgment made at that time. It is not something a cell storage provider can promise now. Using treatment claims in promotional materials as a substitute for checking the contract and records mixes two unrelated things.
If the provider promotes “supporting treatment” or recommends specific medical institutions during sales, keep the storage contract and the medical part separate, and verify each one on its own.
Verify separately when treatment is involved
If you are already considering using stored cells for treatment, what you need to verify is the medical institution, not the storage provider. In Japan, a medical institution providing regenerative medicine must undergo review and submit a regenerative medicine provision plan to the Ministry of Health, Labour and Welfare (MHLW). The MHLW website publishes information on institutions that have submitted provision plans. How to check a medical institution, how to read a provision plan, and how to verify a cell culture processing facility are separate methods and are not covered here. The key point is simple: do not use verification of a storage provider as a substitute for verification of a medical institution.
Verification checklist
| Item to check | Where to look | What adequate information looks like | Warning signs |
|---|---|---|---|
| Storage facility name and location | Website, contract, promotional materials | Has an independent facility name and a specific address | Only a company name; address only down to the city |
| Storage temperature records | Ask the provider, check contract attachments | Has continuous records that can be viewed | Only verbal assurance, no records available |
| Alarm and failure response | Ask the provider, check policy documents | Has a specific procedure and backup plan | Only says “nothing will go wrong” |
| Transport and handover records | Ask the provider | Has handover time, parties, and condition of the material | Transport process is unclear |
| Identification number and record keeping | Contract, ask the provider | Has a unique number and a clear record retention period | Cannot find the history of your cells |
| Storage period clause | Contract | Start and end dates and end-of-period handling are clearly stated | Automatic renewal without notification |
| Fee change clause | Contract | Adjustment conditions and notification method are clear | Not stated, or “to be negotiated” |
| Closure or transfer clause | Contract | Where the cells go and who is responsible are clear | Not stated, or the provider avoids a direct answer |
| Procedures for retrieval and use in treatment | Contract, ask the provider | Procedure, contact point, and confirmation method are clear | Only says “it is simple, we will deal with it later” |
| Promotional content | Website, materials | Only discusses storage and records, does not promise treatment effects | “Can cure disease X in the future” |
Common misconceptions
- Misconception 1: “Having a certification means the service is reliable.” A certification must be checked: who issued it, what it covers, and what it is based on. Seeing a logo is not enough.
- Misconception 2: “The temperature has never had a problem, so the management is good.” No problems is a result. Management is about whether records and an alarm system exist. They are different things.
- Misconception 3: “Once I sign a contract, my cells are safe.” A contract protects the rights and obligations agreed by both parties. It does not mean the facility is operating according to standards. The contract terms themselves also need checking.
- Misconception 4: “The promotion says cells can treat many diseases in the future, so it is worth storing.” Treatment is a medical decision. A storage provider’s promotion cannot make it for you.

Scope of this guide
This guide covers only how to verify information: what documents to look at, what questions to ask, and what claims to be wary of. JRQ does not evaluate whether any specific service is good or bad, does not recommend or certify any service provider, does not evaluate the uses or effects of cells, and does not answer whether storing them is useful. For treatment decisions, consult a doctor and check the medical institution separately using methods for verifying regenerative medicine providers.
