Aim: 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 (ECM). The Read more…
Solid tumors are associated with a modified microenvironment, in particular an enhanced collagen content and increased stiffness at the level of the extracellular matrix (ECM). These ECM changes are now recognized as important drivers of cancer initiation, progression, and propagation, and also impact the responses of cancerous cells to treatments. Read more…

We are very please to annonce our selection in the “CO-INNO INTERNATIONAL” program. Jointly organised by BPI France and Hello Tomorrow, the CO-INNO program accelerates and supports the most cutting-edge French startups from the discovery of the Singaporean ecosystem to the establishment of technological partnerships, funding and even their settlement Read more…
The current hiPSC-derived models are adapted to reproduce diseases of genetic origin in two dimensions and have allowed in recent years to model diseases by using hepatocyte-like-cells (HCL) such as: Alpha1-antitrypsin (A1AT) deficiency (Tafaleng et al., 2015) Familial transthyretin-related amyloidosis (ATTR) (Isono et al., 2014) Glycogen storage deficiency (Satoh et Read more…

Increased ExtraCellular Matrix (ECM) stiffness is a common process in many cancers (Pickup et al, 2014). This process influences the behaviour of cancer cells in the tumour microenvironment. The accumulation of ECM in the stroma is mainly due to a high production of ECM molecules by TGF-β(Transforming Growth Factor-beta) -stimulated Read more…
Historically, cancer has been described as originating from modified cells, because of mutations impacting their growth, their differentiation and their way (not) to die. Now, it is widely acknowledged that the microenvironment surrounding these cells is involved in cancer initiation and progression. As explained in the article by Nia Munn Read more…
Scanning Electron Microscopy (EM) has been an indispensable tool for Biological sciences. A great challenge was propelled by the need to find methods to better preserve and analyze structures at a state closest to the native state. With BIOMIMESYS® hydroscaffold technology, we have developed a new method to use SEM Read more…
HCS Pharma était présent au Workshop OoC pour une création et une structuration de la filière, organisé par Biovalley à l’Institut Pierre-Gilles de Gennes (Paris). Nous sommes très heureux d’avoir pu sponsoriser l’événement, mais aussi tout simplement d’y avoir participé – en présentiel – et de pouvoir discuter avec des chercheurs Read more…
The extracellular matrix (ECM) is a non-cellular component of tissues and organs. It is mainly composed of structural elements (proteoglycans collagens, elastin) and cell adhesion proteins such as fibronectin and laminins. The ECM forms a complex structure with physical properties (elasticity, tensile and compression strength), which provides physical support for Read more…
Ask for high quality link by putting your email below How to make in vitro models predictive of in vivo conditions? By taking into account the 3D cellular organization of in vivo tissues By including the cellular and matricial microenvironments with BIOMIMESYS® By using OoC systems for dynamic in vivo-like Read more…
2022 is beginning, but 2021 ended in the most beautiful way… with Véronique De Conto‘s PhD defense. She successfully defended her PhD thesis about the importance of the microenvironment in cerebral in vitro models for phenotypic screening. We had the privilege to maintain the PhD defense on-site, even if one member Read more…
Maintaining the basal characteristics of primary hepatocytes and HepG2 allows performing metabolic studies. The functional instability of hepatocytes in 2D culture results in a rapid decrease in specific metabolic pathways (Figure 1). Cell culture in BIOMIMESYS® Liver shows higher metabolic characteristics of hepatocytes compared to a culture in 2D, such Read more…
BIOMIMESYS® Liver recreates the complex cellular microenvironment of the liver to extend longevity and functionality of hepatocytes in culture: The life of human primary hepatocytes grown in a 2D sandwich is low, 3-10 days (1) and is accompanied by dedifferentiation, leading to the loss of their functions. In 2D culture, Read more…
In 2020, Nia et al. published in the journal Science a review entitled ‘Physical traits of cancer‘. In this article, the authors proposed 4 distinct physical traits of cancer linked to the biomechanical abnormalities observed in tumoral tissues : an enhanced solid stress (compression and tension), i.e. the mechanical forces Read more…
Hepatotoxicity testing in animals predicts only 50% of liver damage observed in clinical context, in part, because of difference in inter-species hepatic metabolism (1). Therefore, a relevant in vitro model mimicking the micro-environment of the human liver for maintaining and promoting hepatocyte functions, is needed for a better hepatotoxicity prediction Read more…
Pre-adipocytes differentiate into adipocytes through several phases: differentiation and maturation, where they are then completely functional (lipogenesis / lipolysis).
