ESTIV questionnaire on the acquisition and use of primary human cells and tissue in toxicology.

The ability to use human cells and tissues in toxicology research and testing has the benefit that it obviates the need to undertake species extrapolation when assessing human hazard. However, obtaining and using human cells and tissues is logistically difficult, ethically complex and is a potential source of infections to those coming into contact with human cell material. The issue is also controversial, with the recent EU legislation draft on tissue engineering, and also due to some instances of human material being obtained and used without informed consent. There are also varying regulations and attitudes relating to the use of human cells and tissues throughout Member States of the EU, and there is a need for harmonisation. The European Society of Toxicology in Vitro (ESTIV) Executive Board and the European Network of Human Research Tissue Banks (ENRTB) have conducted a survey to ascertain the extent to which human cells and tissues are used by its members, how these are obtained, what local regulations are in force, how the material is used, and the advantages and disadvantages experienced by members in using such material, as opposed to cell lines. The results obtained have been compared with the results from a previous survey conducted in 2000. It is hoped that this information will help to facilitate the process of acquiring and using human cells and tissues in a safe and effective way to promote the use of non-animal approaches for investigating the mechanisms of toxicity, and for predicting the toxic hazard of substances.
