BIOMIMESYS® Liver represents a new generation of mimetic HydroscaffoldS™ for 3D culture of hepatocyte-like cells. Available in a ready-to-use format, it enables the culture of hepatocytes and hepatocyte-like cells under physiological conditions that are representative of the microenvironment found in the liver. The highly porous nature of the Hydroscaffold™ allows the rapid uptake of nutrients, oxygen, etc. into the cells to create a reproducible study model for all downstream analyses used with 3D hepatocyte-like cell culture (metabolism, toxicity…).
IOMIMESYS® Oncology is a new generation of mimetic Hydroscaffolds™ for 3D cell culture. Available in a ready-to-use format, it enables the culture of cells under physiological conditions that are representative of the microenvironment found in whole tissues. The highly porous structure of BIOMIMESYS® allows cells to diffuse into the 3D matrix, where they can fix and begin to develop. The structure and conformation of cells cultured in BIOMIMESYS®, such as cancer cells that spontaneously form spheroids, strongly resemble the structures formed in vivo. Also, the functionality of the BIOMIMESYS® matrix is proved by the expression of genes and proteins at levels that are again more similar to those found in vivo. Cells cultured in BIOMIMESYS® give results that are more physiological than those grown in 2D culture and are closer to those obtained in vivo.
BIOMIMESYS® Adipose tissue represents a new generation of mimetic Hydroscaffold™ for 3D culture of adipocyte and adipocyte-like cells. Available in a ready-to-use format, it enables the culture of adipocytes and adipocyte-like cells under physiological conditions that are representative of the microenvironment found in adipose tissue. The highly porous nature of the scaffold allows the rapid uptake of nutrients, oxygen, etc. into the cells to create a reproducible study model for all downstream analyses used with 3D adipocyte cultures.

Poster : Development of personalized therapeutic targeting in lung cancer wit...HCS Pharma
Abstract: Lung cancer is one of the most frequent cancers in the world with a high mortality rate. The discovery of oncogenic alterations in these cancers allowed the development of targeted therapies against several receptor tyrosine kinases (RTK) including EGFR, ALK or MET and contributed to improve the prognosis of some patients. Mutations impacting the MET receptor exon 14 splice sites (METex14) have recently been detected in about 3% of lung cancers and lead to the loss of the juxtamembrane domain with several negative regulatory sites. METex14 does not lead to constitutive activation of the receptor but we demonstrated that HGF, its ligand, is required for the full development of the transforming capabilities of the METex14 receptor in SCID-HGFhuman transgenic mice.
Several clinical trials have shown that only half of METex14 patients responded to MET inhibitors. While encouraging, these results are lower than those obtained with other treatments such as EGFR inhibitors. Interestingly, METex14 mutations are frequently associated with other molecular alterations including PTEN loss or TP53 mutations. Furthermore, we have shown that many METex14 mutated patients have autocrine secretion of HGF ligand. Understanding how these co-alterations impact METex14 oncogenicity and sensitivity to existing therapies is of outmost importance to identify patients that could benefit from them.
Poster - Including the matricial tumoral microenvironment in 3D in vitro mode...HCS Pharma
In oncology, 97% of drug candidates fail in clinical trials. This highlights a lack of relevance of preclinical models used upstream. Indeed, human in vitro models don’t consider the Tumoral Extracellular Matrix (TECM). However, more and more studies demonstrate that ECM composition and stiffness are modified in tumors and are linked to cancer initiation, progression, propagation, and drug resistances.
BIOMIMESYS® is a Hyaluronic Acid-based matrix grafted with structural and adhesion molecules, which mimics the ECM/TECM. It is chemically defined and its composition and stiffness can be modified to reproduce the organ-specificity of the ECM, or to mimic a pathological microenvironment in vitro.
We have demonstrated that the exposition of colon cancer cells cultured in BIOMIMESYS® Oncology matrix to an anti-proliferative drug showed a closer in vitro/in vivo correlation in the EC50 curve compared to 2D culture. Cancer cells can be advantageously grown in BIOMIMESYS® for several weeks in multiwell plates and in microfluidic chips for more advanced models. We also observed that modifications in the matrix composition and stiffness modify the cell behavior. Moreover, thanks to collaborations with academic laboratories, we demonstrated that BIOMIMESYS® allows to reproduce in vitro the behavior of cancerous cells in vivo, like mutation effects and metastasis propagation, and could be a relevant alternative to animal models. These results showed that the matricial microenvironment modifies the cell behavior in vitro and should be considered carefully in drug discovery. BIOMIMESYS® hydroscaffold™ is adapted to High Content Screening and represented a powerful tool to better select drug candidate.

HCSPHARMA Importance of microenvironment in cerebral in vitro models for phen...HCS Pharma
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 objective was to study the influence of the microenvironment in cerebral in vitro models, in the frame of Parkinson’s Disease (PD).
Methods: First, we analyzed the influence of astrocytes on Luhmes cell sensitivity, a dopaminergic neuronal cell line, in 2D culture. Then, we developed a hyaluronic acid-based hydroscaffold for 3D cell culture, which mimics the ECM, and study the sensitivity of Luhmes cells in this model. Thirdly, we performed a co-culture of Luhmes cells and astrocytes in this matrix, to form a complex model including both the glial and the matricial microenvironments.
Results: We observed a protective effect of astrocytes in 2D culture. In the hydroscaffold, Luhmes cells displayed a lower sensitivity compared to 2D culture, that was explained by a partial retention of toxic molecules in the matrix, and differences in neuronal protein expression. In the co-culture, we observed spheroids containing both neurons and astrocytes.
Conclusions: This work highlighted that the microenvironment of neurons can modify the neuronal response in vitro, and should thus be considered carefully in academic research and in drug discovery. This model can be now used to study the microenvironment modifications in pathological conditions, and to develop innovative drugs targeting the microenvironment.

Growing interest in phenotypic screening, together with evidence that the drug response of cells grown in three-dimensional (3D) structures more closely resembles in vivo activity, has made high throughput, 3D fluorescence imaging an attractive screening option for drug discovery. However, creating 3D spheroids compatible with high content screening can be a difficult and expensive process.
BIOMIMESYS® is a range of patented hyaluronic acid scaffolds for 3D cell culture. They are made of RGDS- and galactosaminegrafted hyaluronic acid, using an adipic acid dihydrazide crosslinker and extracellular matrix proteins (eg. type I, IV or VI collagen) to accurately mimic the in vivo extracellular environment. BIOMIMESYS® is suitable for automated testing thanks to the uniform thickness of the scaffold – around 650 μm – with an average porosity of 100 to 200 μm
This application note describes a straightforward workflow for 3D cell seeding and spheroid formation using HCS Pharma’s BIOMIMESYS® plates in combination with INTEGRA’s VIAFLO 96/384 pipetting system.

While the direct link between hiPSCs and patients, as well as the abundance of HLCs provide promising advantages of such strategy, it is impaired mainly by the neonatal characteristic of HLCs as well as the difficulty to perform high throughput studies for pharmacological investigations.
Therefore, to overcome these burdens, we choose to 1. Differentiate hiPSCs into HLCs in a 3D environment instead of the classical 2D culture systems to enhance their maturation; 2. Adapt our 3D differentiation process to a 96 wells format to make it compatible for drug screening.
To reach our goals, we established a partnership with HCS Pharma, which has an expertise in high content phenotypic screening and produces an innovative 3D scaffold, BiomimesysTM. This scaffold is composed of hyaluronic acid that can be functionalized with extra cellular matric derivatives, with adjustable stiffness and porosity. We setup conditions for hiPSCs seeding and differentiation to reach a new protocol adapted to a 3D environment. Our preliminary data indicate that our procedure enhanced expression of hepatic markers such as transcription factors (FOXA2, FOXA3, HNF1a, HNF1b, HNF4a), cytochrome P450 (CYP450) family members (CYP3A4, CYP2A6, CYP7A1) or cholesterol metabolism regulators (PCSK9, Lipoprotein(a)). During our presentation, we will discuss our data hiPSCs differentiation in 3D, CYP450 activities and induction, as well as their application for the study of metabolic diseases.
Neurotoxicity assessment: Comparison between SH-SY5Y and iPSC-derived cellsHCS Pharma
As shown by AstraZeneca in Nature reviews*, one third of the safety failures is linked to CNS toxicity during the clinical trials of drugs. Therefore, relevant in vitro human model is needed to detect early neurotoxicity of drug candidates. In this study, sensitivity of iPSC-derived neuronal cells to 32 compounds is compared to the sensitivity of SH-SY5Y cells. Two types of iPS-derived cells are tested: central nervous system cells (CNS.4U™ cells) and peripheral nervous system cells (PERI.4U™ cells) from Ncardia. Toxic effects are then measured by HCS cell imaging.

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 patients with a well-described phenotype and carrying specific genotypes. This non-invasive approach allowed the study of LDLR- and PCSK9-mediated autosomal dominant hypercholesterolemia (ADH) as well as PCSK9-mediated familial hypobetalipoproteinemia (FHBL). While the direct link between hiPSCs and patients, as well as the abundance of HLCs provide promising advantages of such strategy, it is impaired mainly by the neonatal characteristic of HLCs as well as the difficulty to perform high throughput studies for pharmacological investigations.

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 patients with a well-described phenotype and carrying specific genotypes. This non-invasive approach allowed the study of LDLR- and PCSK9-mediated autosomal dominant hypercholesterolemia (ADH) as well as PCSK9-mediated familial hypobetalipoproteinemia (FHBL). While the direct link between hiPSCs and patients, as well as the abundance of HLCs provide promising advantages of such strategy, it is impaired mainly by the neonatal characteristic of HLCs as well as the difficulty to perform high throughput studies for pharmacological investigations.
Therefore, to overcome these burdens, we choose to 1. Differentiate hiPSCs into HLCs in a 3D environment instead of the classical 2D culture systems to enhance their maturation; 2. Adapt our 3D differentiation process to a 96 wells format to make it compatible for drug screening.
To reach our goals, we established a partnership with HCS Pharma, which has an expertise in high content phenotypic screening and produces an innovative 3D scaffold, BiomimesysTM. This scaffold is composed of hyaluronic acid that can be functionalized with extra cellular matric derivatives, with adjustable stiffness and porosity. We setup conditions for hiPSCs seeding and differentiation to reach a new protocol adapted to a 3D environment. Our preliminary data indicate that our procedure enhanced expression of hepatic markers such as transcription factors (FOXA2, FOXA3, HNF1a, HNF1b, HNF4a), cytochrome P450 (CYP450) family members (CYP3A4, CYP2A6, CYP7A1) or cholesterol metabolism regulators (PCSK9, Lipoprotein(a)). During our presentation, we will discuss our data hiPSCs differentiation in 3D, CYP450 activities and induction, as well as their application for the study of metabolic diseases.
Neurotoxicity assessment: Comparison between SH-SY5Y and iPSC-derived cellsHCS Pharma
As shown by AstraZeneca in Nature reviews*, one third of the safety failures is linked to CNS toxicity during the clinical trials of drugs. Therefore, relevant in vitro human model is needed to detect early neurotoxicity of drug candidates. In this study, sensitivity of iPSC-derived neuronal cells to 32 compounds is compared to the sensitivity of SH-SY5Y cells. Two types of iPS-derived cells are tested: central nervous system cells (CNS.4U™ cells) and peripheral nervous system cells (PERI.4U™ cells) from Ncardia. Toxic effects are then measured by HCS cell imaging.
