We are pleased to participate to the 21st International Congress of the European Society of Toxicology In Vitro (ESTIV 2022), which will take place in Barcelona-Sitges, Spain, from 21st to 25th November 2022. Our project Leader in in vitro pharmacology Véronique De Conto will present her poster entitled “In vitro microenvironment modifies the neurotoxic Read more…
Présentation en français About 90% of drug-candidates failed in clinical trials, in particular in neurology, due to a lack of efficacy. That highlights a lack of relevance in preclinical models, including in vitro models, which do not take into account the microenvironment, composed by glial cells and the Extracellular Matrix Read more…
In the brain, we have about 100 billion of neurons but they represent only 10 to 50% of the total cells (von Bartheld et al., 2016). Indeed, glial cells, including astrocytes, oligodendrocytes and microglia are also essential to the physiological functions of the brain. Parkinson’s Disease (PD) is the secondary Read more…
Pharmaceutical industry is facing a very high failure rate in drug discovery, with 90% of failure in clinical trials. This is particularly true for central nervous system applications, with a rate of 30% safety failure in clinical trials, compared to 7% in preclinical trials (Cook et al. 2014). This reveals Read more…

The human brain contains approximately 86 billon neurons of different types, distributed and organized in different areas ; their functions vary according to the neuron type and its localization within the brain. However, the neuronal function also depends on its microenvironment, which is composed of the extracellular matrix (ECM), and Read more…
The neurovasculaire unit (NVU) is composed of brain microvascular endothelial cells (BMECs) that form the Blood-Brain-Barrier (BBB), pericytes, neurons and glial cells. It regulates substance transport between blood and brain. BBB and NVU dysfonctions are associated with numerous neurological pathologies. Animal models are traditionally used in medical research but the Read more…
The first version of BIOMIMESYS Brain allows to form neurospheres. We now developped a new version of BIOMIMESYS Brain, which allows to form neuronal networks. This version have a higher porosity than BIOMIMESYS Brain (Neurosphere), that allows to better disperse the cells and thus to form cell network instead of Read more…
HCS Pharma is one of the winner of the Lab’StartUp village, organized by Forum Labo! As such, we have won a stand in the heart of the forum (March 26-28, 2019)… Thanks a lot to the committee for evaluating our application to this prize, and for selecting our new product Read more…
Sood et al. published in 2016 an interesting article about the effect of extracellular matrix (ECM) on in vitro neuronal cells culture: “Fetal brain extracellular matrix boosts neuronal network formation in 3D bioengineered model of cortical brain tissue “. The aim of the study was to study the effects of Read more…
We are developing a new BIOMIMESYS® hydroscaffold for neuronal cells. First results are very promising because neurons grow and form neurites. Moreover cells lived longer than in monolayer culture. We are currently finalizing this new hydroscaffold to find the best conditions of 3D neuron culture, but BIOMIMESYS® Brain will be soon Read more…
One third of the safety failures is linked to CNS toxicity during the clinical trials of drugs. In order to develop a more predictable in vitro human model for neurotoxicity testing, we have compared the sensibility of iPSC-derived neuronal cells and SH-SY5Y cell line (neuroblastoma-derived cell line) to a panel Read more…
