Around the world, there may be in excess of 300 human embryonic stem (hES) cell lines. The status of these ranges from those of low passage (and thus unproven in experimental work) to those which have been formally prepared as large quality-controlled stocks and made available to researchers. However, many of these lines have yet to be fully characterised and formally published. Stem cell banks that are focused on making reproducible quality-controlled stocks widely available to researchers play an important role. Their job is to help sustain the availability of cell cultures which can be traced to, and still show the same characteristics as, original published cell lines as well as useful derivatives or clones.

It is important to recognise that the phrase ‘stem cell bank’ can refer to a number of different levels and types of operation. This wide spectrum is illustrated in Table 2.

Service culture collections can provide numerous benefits to stem cell researchers, including:

It is important that people or organisations acting at this level should be well coordinated, to help disseminate best practice, enhance international standardisation and promote the international availability of reproducible and authentic stem cell cultures. Historically, there have been numerous incidences of non-hES cell lines being switched with, or cross-contaminated by, other cell types. This has caused deleterious microbial contamination, invalidated research work and wasted investment in new cell-derived products. It is crucial that this is not repeated with hES stem cell lines, as it could delay the progress of future therapies. Well-coordinated stem cell banks could greatly reduce the impact of these issues.

Table 2 - Stem cell banks for research, production and clinical use

Type of supply of stem cell lines Primary activities
Local laboratory stocks for research
  • Satisfying demand for undifferentiated cells for experimental use
Centralised institute stocks for research
  • Provision of cultures or frozen cells to a number of laboratories
  • Basic quality control
  • Characterisation usually in individual laboratories
National supply of hES cells for a broad range of researchers
  • Establish large stocks of reproducible, well-characterised and quality-controlled cells
  • Provide safe storage as a back up for originators of lines
  • Distributed cells should meet national best practice safety guidelines (for example, screened for serious common blood-borne pathogens)
  • Operate under a published Code of Practice
  • Ensure recipients and their use of lines meet the demands of national regulations
  • Engage in other national resource and training programmes
International stem cell bank

As for national banks, but with the following additional safeguards:

  • Ensure compliance of deposited lines and distribution with all national guidance, regulation and laws of depositors and recipients (ideally thorough a high level oversight body)
  • Have in place a rigorous quality assurance system that will assist in the delivery of reproducible and reliable cells and service
  • Coordination with other national banks to promote best practice
Tissue bank supplying stem cell for transplantation (for example; bone marrow, cord blood and mobilised peripheral blood stem cells)
  • Donor screening, including blood tests for viral markers
  • Fully informed consent on donated material
  • Rigorous quality assurance under national guidelines
  • Validation of bank processing procedures
  • Compliance with regulation including appropriate national or international inspections
Master and working cell banks for pharmaceutical production of medicinal products from cell lines
  • Delivery of cells for a specific end product 
  • Donor selection and informed consent if appropriate (new human cell lines)
  • Preparation under a product license in accredited cGMP facilities
  • Exhaustive accredited safety testing and quality control

Current coordination of stem cell banks

The UK Stem Cell Bank (UKSCB) has had a variety of formal and informal contacts with scientific and government representatives from all ISCF member countries, including specific discussions on cell banking. There appears to be a general desire for greater coordination between the centres carrying out banking of stem cell lines. Some activities are already moving forward. For example, the International Society for Stem Cell Research standards committee asked the UKSCB to prepare a list of centres actively distributing hES cell lines for research.

A brief summary of current stem cell banking activity is given in Table 3.
