How to deposit Stem Cells in the UK Stem Cell Bank

These notes are intended as a step-by-step guide to depositing human stem cells in the UK Stem Cell Bank.

It is assumed that you will have read the relevant sections of The Code of Practice for the Use of Human Stem Cell Lines.  The current version of this document is available on both the MRC’s and the Bank’s websites.  It is a requirement that embryonic stem cell lines derived in the UK under an HFEA licence are lodged with the UKSCB.  Overseas depositors should also read the sections of the Code of Practice relating to consent and ethical issues.  

 

Step 1: Complete the application form.  

An application to deposit form should be submitted to the UK Steering Committee through the MRC Secretariat at the address given below.  

The UKSCB is not involved at this stage and to avoid delays, it is advisable to contact the MRC Secretariat ahead of completing the application form. They will advise you of any supporting information that may be required by the UK Steering Committee to assess your application.  

The decision to accept a cell line for deposition into the UKSCB is made by the UK Steering Committee on the basis of the application form you provide together with any additional information requested by it.

 

Step 2: Contact with the Bank.

Once your application to deposit has been approved by the UK Steering Committee, the MRC Secretariat will notify you through its approval letter. This will be copied to the Bank and you should expect to hear from a member of our team within the following two weeks.

However, in order to minimise delay, it is advisable to establish contact with the Bank even before receiving your letter of approval.

A member of our team will be able to advise you on relevant legal agreements and other documents specific to the cell line(s).

 

Step 3: Complete and sign relevant documents.

Subject to approval obtained by the UK Steering Committee, you will be contacted by a member of the UKSCB and you will be presented and asked to sign up to three copies of the Material Deposition and Distribution Agreement (MDDA). In some cases additional information specific to the cell line needs to be captured under a separate technical agreement. All those documents named above will be provided by the UKSCB in due course.

Failure to sign the MDDA may contribute and delay the process of distribution of your cell line(s) through the UKSCB. To avoid delays, you may download and review legal agreements from the Bank’s website.

 

Step 4:  Formally accessioning the cell line(s) into the UKSCB.  

 

The process of accessioning involves:

  • gathering information;
  • receiving technical training (where required);
  • identifying a suitable stock of cell material for transfer into the bank;
  • undertaking a risk assessment

 

Gathering information:

You will need to complete the Bank’s Cell Line Information Form. It is important that this information is a correct and up-to-date record of how your cells are cultured as this document forms the basis for the methods by which we bank your cell line(s).  The form will also become part of the Cell Line Master File for your cell line: the base document for Quality Assurance and audit of your cell line.  

We will also be asking you for copies of any protocols and procedures that you may use in order to provide the detail required for our Standard Operating Procedures (SOPs).  All protocols and procedures you provide will be treated in confidence, but we would request that you make us aware of any areas that you consider to be commercially sensitive.  

You should complete and check the form carefully, sign and return the form to the Bank. 

 

Receiving technical training:

In some cases, the Bank may follow up its initial telephone and e-mail contacts by visiting your laboratory to talk to you and your staff in more detail about your cell line.  Where appropriate, the Bank may also make contact with the IVF centres involved in the derivation of the cell line. The purpose of this contact is to understand the derivation and initial culture procedures.  Donor anonymity will be respected at all times and the Bank will seek no information likely to compromise this during such visits.  

We will also discuss with you whether there are any perceived training requirements for Bank staff and how this may best be obtained should this prove necessary.  In certain circumstances (e.g. some overseas deposits) it may not be possible to carry out a laboratory visit.  In these circumstances, the Bank will discuss with you the best course of action to allow the Bank to gain the necessary expertise.

 

Identifying a suitable stock of cells for transfer to the UKSCB:

The Bank only takes in frozen (or vitrified) material.  Ideally, we would like a minimum of six ampoules or straws all frozen from the same passage.  Generally, this should be from the earliest passage that you believe best represents the cell line you have derived and which you know is capable of generating a fresh stock of stem cells.  There should also be sufficient stock from this passage left over for you to archive material locally for future reference.  The material provided should be from those stocks of cells that were produced and banked under the protocols and procedures that you supplied to the Bank.  

We will also discuss with you whether it would be beneficial to bank any feeder cells associated with your stem cell line and also, whether it would be beneficial to receive and test (for sterility and mycoplasma) some material in advance of your cell line(s) coming into the Bank.  

 

Undertaking a cell line risk assessment:

Once the Project the information on your cell line is complete the Bank will undertake a risk assessment.  This will involve UKSCB staff and advisors and will decide the panel of tests to be carried out on your cell line(s).  The UKSCB undertakes a core panel of characterisation and safety tests but uses the risk assessment to generate its full testing strategy.  This will be more extensive (particularly in the area of viral testing) for cell lines that may have therapeutic potential (so called “Clinical Grade” cell lines).  You, as the depositor, may be asked for your comments on the testing strategy developed for your cell line or asked to provide further information.  

 

Step 5:  Receiving cells at the Bank.  

Prior to taking in the stock of cells, we will discuss with you the best method of shipping the material to the Bank.  This may involve us in collecting the deposit from you, or arranging for collection by a third party.  In either case, the cost of transportation will be borne by the Bank.  

We may, from time to time during the banking process, contact you with additional technical questions.  Also, if you have requested it, we will return a sample from our distribution bank to you for testing.  If we find an inconsistency between data you have supplied and data we have generated during quality control testing, we will discuss this with you prior to releasing the cells and placing data on the cell line on our website.
