The Fraunhofer Translational Center for Regenerative Therapies (TLC-RT) is taking over the epiCS® technology from Henkel AG & Co. KGaA, thereby ensuring the continued availability of internationally standardized epidermis models. These OECD-validated tissue models offer a reliable alternative for evaluating the skin reactions of chemical substances and contribute to the safety of cosmetics and pharmaceuticals.
Three-dimensional tissue models of the human epidermis can be used to evaluate chemical substances, cosmetics, or pharmaceuticals for their potential to cause irritation or damage, as well as for dermatological, pharmaceutical, and cosmetic research. The Fraunhofer Translational Center for Regenerative Therapies (TLC-RT) at the Fraunhofer Institute for Silicate Research ISC has long been active in research and development for functional, three-dimensional tissue models.
Such models must be approved for toxicological evaluation in accordance with internationally applicable OECD guidelines. The epiCS® technology provides a system of epidermis models and test protocols for determining the skin irritation and skin corrosion potential of active substances, which has been validated according to internationally recognized standards. The protocols are part of OECD Test Guidelines 431 (in vitro skin corrosion testing) and 439 (in vitro skin irritation testing) and thus offer a validated alternative to animal testing.
The epiCS® technology previously offered by Henkel AG & Co. KGaA is now being taken over by Fraunhofer TLC-RT. “This step is the result of many years of cooperation and intensive knowledge transfer between Henkel AG & Co. KGaA and Fraunhofer TLC-RT,” says Prof. Florian Groeber-Becker, head of TLC-RT. “While the validated epiCS® epidermis model is essential for regulatory safety testing, we are continuing to develop advanced in-house skin models for specific research questions. This enables us to create a broad testing platform, from standard approval to complex skin models for individual research questions,” Groeber-Becker continues.
The success of the method transfer was verified by extensive testing to ensure the high quality of the tissue and the test procedures based on it at the new production site. Dr. Dieter Groneberg, Group Leader of the “Skin” working group at Fraunhofer TLC-RT confirms: "The epiCS® epidermis models will thus continue to be available for research projects and industrial applications. This means that one of the most powerful epidermis models ‘Made in Germany’ will be preserved." The tissues, which are produced entirely in the laboratory, enable precise, reproducible tests and thus make an important contribution to product safety. The Fraunhofer TLC-RT thus underscores its commitment to innovative technologies that promote ethical standards in research and support the scientific use of skin models as an alternative to animal testing (New Approach Technologies).

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
