We previously showed that human pluripotent stem cells (hiPSCs) provide a suitable model to study metabolic diseases upon hepatocyte-like cell (HLC) differentiation. In particular, HLCs have been used to model cholesterol metabolism regulation, by mimicking the main disease features in vitro. Human iPSCs can be generated from urine samples of Read more…

Most potential drug candidates (90%) fail within the clinical trials, mainly because of lack of efficacy. What if the pharmaceutical industry uses predictive human in vitro models in early drug discovery ?

Therefore, relevant in vitro human models are needed to detect early neurotoxicity of drug candidates. In Read more…
Human induced pluripotent stem cells (hiPSC) are becoming a relevant model for the study of liver metabolic diseases once differentiated into hepatocyte-like cells (HLC), and it has been shown that they can faithfully recapitulate autosomal dominant hypercholesterolemia (ADH). PCSK9 is a critical modulator of cholesterol homeostasis, and quickly became a Read more…

Cell biology is part of the R&D activity in dermocosmetology, as providers of active extracts or pure compounds have to demonstrate their efficacy and safety. At HCS Pharma, we are developing new dermocosmetology assays on relevant cellular models, like human primary keratinocytes and human primary fibroblasts, using our automated platform and high content analysis system.
Méryl Roudaut* will present a poster on the work of Institut du Thorax
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.
Quantifying DNA damage is mandatory to assess potential adverse effects of candidate, drugs, molecules or extracts developed in dermo-cosmetic industry. Different assays can be performed to detect primary DNA damages, such as γH2AX or the single cell gel electrophoresis also known as the comet assay.
As shown by AstraZeneca in nature reviews, one third of the safety failures is linked to CNS toxicity during the clinical trials of drugs .
The creation of a double strand break (DSB) is accompanied by the phosphorylation of histone H2AX. The measurement of serine 139 phosphorylated histone H2AX (γH2AX) is reported to be a marker of interest to identify potential genotoxic activity.
Quantifying DNA damage is mandatory to assess potential adverse effects of candidate drugs or molecules or extracts developed in the dermo-cosmetic industry, but also to assess the efficacy of therapeutic approaches with the aim of producing tumor cell genotoxicity in cancer treatment.
To find anti-cancer drugs, different cellular modifications can be looked at: cell death effect on proliferating cells either in 2D culture or on spheroids (3D culture), anti-mitotic, anti-migration/invasion, anti-angiogenesis effects… Different assays can be performed to follow these different effects. High content screening is a multi-parametric technology allowing searching for poly-effects drugs.
