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…
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…
A new BIOMIMESYS® hydroscaffold is available for 3D cell culture! This hydroscaffold is suitable for neuronal cell culture. We tested it for two cell lines: SH-SY5Y cells, commonly used for pharmaceutical research, and LUHMES cells (dopaminergic neurons). Cells grow and form spheroids with intra and inter-spheroidal neurites. BIOMIMESYS® hydroscaffold allows 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…
