La carte de la Cosmetic Valley

HCS Pharma is now member of the Cosmetic Valley competitiveness cluster, the worldwide leader in perfumery and cosmetics resources, skills, research and training.

Cosmetic Valley was designated a “competitiveness cluster” by the Inter-ministerial Committee for the Development and Competitiveness of Regions (CIACT) on July 12, 2005. Today it is the worldwide leader in perfumery cosmetics resources and contributes to the development of the perfumery cosmetics sector with more then 800 companies for approximately 70,000 jobs and €11 billion in revenue !

With the backing of local authorities, Cosmetic Valley leads a network of businesses and research and training centres committed to a joint approach based on a dynamic focused on innovation.

HCS Pharma is really happy to be now part of this cluster, as our dermocosmetology services are focused on innovation and new efficient technologies (like HCS). It’s a pleasure to meet and talk with researchers of the cosmetology field.

Genotoxicity potential assessment of pharmaceuticals is mandatory for registration. In addition to the standard in vitro/ in vivo test battery, other assays can be of interest because of their high throughput in the drug discovery stage but also for mechanistic understanding.

Different other assays can be performed to detect DNA damage, such as γH2AX and the single cell gel electrophoresis (or comet assay).

keratinocyte2The γH2AX assay was suggested as a new in vitro assay for detecting genotoxic properties of chemicals. The phosphorylation of γH2AX has been demonstrated to be a sensitive marker for a wide range of DNA damage. In this study, primary human keratinocytes were evaluated to provide a more relevant testing system for genotoxicity assessment in the skin for topical dermatological/cosmetic substances. Primary human keratinocytes were compared to the well known HepG2 cell line for which data have already been published.

The comet assay is a sensitive, well established technique for quantifying DNA damage in eukaryotic cells and enabling the detection of a wide range of DNA damaging agents. The assay can be adapted in a 96 wells format allowing higher throughput.

The high content imaging (HCI) analysis applied to genotoxicity assays is a valuable tool allowing higher throughput and multi-parametric analysis in order to improve predictability of these assays.
