Poster – (ECM 2022) Development of innovative hiPSC-based model including an innovative 3D modified hyaluronic acid hydroscaffold for phenotypic screening

We previously showed that human pluripotent stem cells (hiPSCs) provide a suitable model to studymetabolic diseases upon hepatocyte-like cell (HLC) differentiation. With a non-invasive approach, hiPSCs can be generated from urine samples of patients and HLCs have been used to model cholesterol metabolism regulation, by the study of LDLR- and Read more…

Human liver organoids and disease models, it’s time to use a more realistic ECM

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…

Cellular structures in BIOMIMESYS® hydroscaffold using Scanning electron microscopy (SEM): example of liver cells

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…

A single procedure to generate functional hiPSCs-derived liver organoids -Towards an innovative tool suitable for drug screening

The current hiPSC-derived models are adapted to reproduce diseases of genetic origin. However, the current two-dimensional HLC (hepatocyte like-cells) model has an immature liver phenotype that is more is closer to a perinatal liver. Furthermore, it does not take into account the complexity of the tissues and the extracellular environment Read more…

Poster – A single procedure to generate functional hiPSCs-derived liver organoids -Towards an innovative tool suitable for drug screening

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 Read more…

Importance of the liver extracellular matrix in the development of NASH/ASH

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…

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…

We will present our work about the generation of functional human liver organoids with BIOMIMESYS® in CNRS thematic school

This week we will present at the thematic school “From 3D culture to the organoid: multidisciplinary research” organised by the Institute of Biological Sciences of CNRS (France) in Strasbourg. Study director Méryl Roudaut will talk about the generation of functional human liver organoids using hiPSC and our innovative 3D cell Read more…
