Importance du microenvironnement dans les modèles cérébraux in vitro pour le criblage phénotypique

Presentation in english Environ 90 % des candidats médicaments échouent aux essais cliniques, notamment en neurologie, faute d’efficacité. Cela met en évidence un manque de pertinence dans les modèles précliniques, y compris les modèles in vitro, qui ne prennent pas en compte le microenvironnement, composé par les cellules gliales et Read more…

Poster – (ECM 2022) Development of innovative hiPSC-based model including an innovative 3D modified hyaluronic acid hydroscaffold for phenotypic screening

We previously showed that human pluripotent stem cells (hiPSCs) provide a suitable model to studymetabolic diseases upon hepatocyte-like cell (HLC) differentiation. With a non-invasive approach, hiPSCs can be generated from urine samples of patients and HLCs have been used to model cholesterol metabolism regulation, by the study of LDLR- and Read more…

New article published for Nanostem project about the interaction between nanoparticles and the blood-brain barrier in vitro

To treat brain disease is a challeging purpose, since the brain is protected by a barrier made by of tightly-joined endothelial cells of the cerebral microvessels, called the blood–brain barrier (BBB). To improve this route to reach the central nervous system, several strategies have been developed. Among them, researchers try Read more…

Poster – A single procedure to generate functional hiPSCs-derived liver organoids -Towards an innovative tool suitable for drug screening

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…

BIOMIMESYS® Adipose tissue

Regulation of lipid accumulation : application with BIOMIMESYS® Adipose tissue

Retinoic acid and Caffeine are reference molecules known for their inhibitory activity on lipogenesis. Retinoic acid, a derivative of vitamin A, inhibits adipogenesis by blocking adipogenic factors such as PPARγ2 and C / EBPα, via the Retinoic acid receptor (RAR) ligand (1). Caffeine, a non-selective adenosine antagonist receptor, is used Read more…

BIOMIMESYS® Adipose tissue

Increased expression of differentiation genes with BIOMIMESYS® Adipose tissue

The morphological changes in cells during differentiation are accompanied by a profound change at the molecular level. In vivo, the adipocyte differentiation process includes early and late events due to differential gene regulation. The appearance of these markers is a sign of differentiation of pre-adipocytes and hence the development of Read more…

BIOMIMESYS® Adipose tissue

Higher lipogenesis activity with BIOMIMESYS® Adipose tissue

Triglycerides (TGs) are an efficient form of fatty acids to accumulate as energy reservoirs or as building blocks for membrane lipid synthesis. In adipose tissue, TGs are continuously synthesized during lipogenesis. In order to measure the lipogenesis activity of 3T3-L1 and mature human adipocytes, Adipored™ staining and Perilipin immunocytochemistry were Read more…
