Importance of the microenvironment in cerebral in vitro models for phenotypic screening (Abstract of Veronique’s thesis)

About 90% of drug candidates fail in clinical trials, for efficacy- and toxicity-related reasons, which often involve the Central Nervous System (CNS). This high failure rate highlights a lack of relevance in experimental models used upstream, including human in vitro models. Indeed, they do not take into account the complexity Read more…

Collaboration between “Institut du thorax” and HCS Pharma: improving the management of hypercholesterolemia using a relevant and innovative organoid-based in vitro liver model

Launched in 2016, the adventure is coming to an end after 5 years of work carried out within the RHU CHOPIN (CHOlesterol Personalized INnovation), and with a strong collaboration between HCS Pharma and l’Institut du thorax. This collaborative project of national scope was led by Professor Bertrand Cariou, director of Read more…

On the importance of extracellular matrix of the skin for efficient 3D cell culture models

The extracellular components of the skin can be divided into fiber-forming structural molecules, nonfiber-forming structural molecules, and “matricellular proteins”. Optimal quantities of different matrix components and their delicate interactions are necessary to maintain normal physiologic properties of the skin. Fiber-forming molecules provide a structure to the ECM by creating a Read more…

The key role of appropriate microenvironnement in your 3D cellular assays

Context It is well established that the extracellular matrix (ECM) plays a central role in cell homeostasis and cell adhesion by providing support, promoting cell-to-cell communication and differentiation (or dedifferentiation and tumoral progression when the ECM is modified). The composition but also the stiffness and elasticity of the ECM have important Read more…

Impact of neurodegenerative diseases on extracellular space organization and diffusion through hyaluronan remodeling

Soria et al. has published this year an interesting study about the modification leading by synucleopathy on the nanoscale organization and diffusivity of the extracellular space, through hyaluronan remodeling. Indeed the extracellular space (ECS), composed by the interstitial fluid and the extracellular matrix (ECM), plays several roles in health and Read more…

3D co-culture of dopaminergic neurons and astrocytes in BIOMIMESYS® Brain to study Parkinson’s disease

Parkinson’s disease affects more than 6 million people worldwide. This neurodegenerative disease is characterized by the death of dopaminergic neurons in the substantia nigra pars compacta, with intracellular accumulation of alpha-synuclein aggregates known as Lewi bodies. This neuronal loss leads to a decrease in the neurotransmitter dopamine that cause mainly Read more…
