Recommendations to improve the EU non-technical summaries of animal experiments.

ALTEX 2018 29;35(2):193-210. Epub 2017 Nov 29.

Animal Welfare Academy, German Animal Welfare Federation, Neubiberg, Germany.

Under the new Directive 2010/63/EC, member states have to publish non-technical summaries (NTS) of the projects involving animals that they authorise. These summaries must include information on the objectives of the project including the predicted harm and benefits and the number and types of animals to be used. Summaries should also demonstrate compliance with the 3Rs. The intention was that NTS would help increase the transparency of animal research in the EU. In this article, we review the status of the publication of NTS across member states and give some general observations on publication speed, identification, accessibility and quality. We also review in more detail the quality of reporting in a selection of NTS from Germany and the UK. We consistently found that NTS from Germany and the UK were deficient in their description of what is being done to the animals and what they might experience as a result. Using examples taken from specific NTS we highlight what we view to be good and bad examples to assist member states and researchers in producing better NTS in the future. The NTS can also be an important tool in sharing of best practice in the 3Rs and the avoidance of duplicative animal testing. For this to happen however, member states need to publish timely, ensure that NTS are accurate and, ideally, there needs to be some centralisation of the NTS.

Fetal Bovine Serum (FBS): Past - Present - Future.

ALTEX 2018 9;35(1):99-118. Epub 2017 Aug 9.

Division of Physiology, Medical University Innsbruck, Innsbruck, Austria.

The supplementation of culture medium with fetal bovine serum (FBS, also referred to as "fetal calf serum") is still common practice in cell culture applications. Due to a number of disadvantages in terms of quality and reproducibility of in vitro data, animal welfare concerns, and in light of recent cases of fraudulent marketing, the search for alternatives and the development of serum-free medium formulations has gained global attention. Here, we report on the 3rd Workshop on FBS, Serum Alternatives and Serum-free Media, where regulatory aspects, the serum dilemma, alternatives to FBS, case-studies of serum-free in vitro applications, and the establishment of serum-free databases were discussed. The whole process of obtaining blood from a living calf fetus to using the FBS produced from it for scientific purposes is de facto not yet legally regulated despite the existing EU-Directive 2010/63/EU on the use of animals for scientific purposes. Together with the above-mentioned challenges, several strategies have been developed to reduce or replace FBS in cell culture media in terms of the 3Rs (Refinement, Reduction, Replacement). Most recently, releasates of activated human donor thrombocytes (human platelet lysates) have been shown to be one of the most promising serum alternatives when chemically-defined media are not yet an option. Additionally, new developments in cell-based assay techniques, advanced organ-on-chip and microphysiological systems are covered in this report. Chemically-defined serum-free media are shown to be the ultimate goal for the majority of culture systems, and examples are discussed.
