Poster – Development and automation of 3D innovative hiPSC-based liver organoids including the microenvironment for phenotypic screening – Application on metabolic diseases

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…

Poster – Development of a new liver-on-chip including BIOMIMESYS® technology for mimicking the liver extracellular matrix: first results and perspectives

Objective: to develop a new liver-on-chip model that includes a relevant 3D matrix for hepatic cell growth and function with the use of of BIOMIMESYS® Liver hydroscaffold for a physiological 3D hepatocyte culture.

BIOMIMESYS® Oncology is a relevant hydroscaffold for cancer-related in vitro studies

BIOMIMESYS® Oncology is mostly composed of hyaluronic acid (HA), biofunctionnalized with undenaturated collagen I. HA, by interacting with its binding proteins (CD44, RHAMM, ICAM-1), is an active participant in inflammatory, angiogenic, fibrotic and cancer-promoting processes (Figure 1). We are currently looking at the effect of different elastic moduli of BIOMIMESYS® Read more…

Poster – A groundbreaking 3D cell culture technology for HCS: BIOMIMESYS hydroscaffold

Most potential drug candidates (90%) fail within the clinical trials, mainly because of lack of efficacy.  What if the pharmaceutical industry uses predictive human in vitro models in early drug discovery ?

Direct Effect of Bevacizumab on Glioblastoma Cell Lines In Vitro

Abstract  Bevacizumab is a humanized monoclonal antibody directed against the pro-angiogenic factor vascular and endothelial growth factor-A (VEGF-A) used in the treatment of glioblastomas. Although most patients respond initially to this treatment, studies have shown that glioblastomas eventually recur. Several non-mutually exclusive theories based on the anti-angiogenic effect of bevacizumab Read more…

Three Dimensional Tumor Engineering by Co-Culture of Breast Tumor and Endothelial Cells Using a Hyaluronic Acid Hydrogel Model

Abstract Besides tumor cells, the microenvironment harbors a variety of host-derived cells. To date, the most successful tissue engineering approaches have employed methods that recapitulate the composition, architecture and/or chemical presentation of the native microenvironment. Thus tumor engineering in biomimetic three dimensional conditions represents a dynamic cooperatively between different cell Read more…

Survival of cord blood haematopoietic stem cells in a hyaluronan hydrogel for ex vivo biomimicry

Abstract Haematopoietic stem cells (HSCs) and haematopoietic progenitor cells (HPCs) grow in a specified niche in close association with the microenvironment, the so‐called ‘haematopoietic niche’. Scaffolds have been introduced to overcome the liquid culture limitations, mimicking the presence of the extracellular matrix (ECM). In the present study the hyaluronic acid Read more…

Hyaluronan hydrogel: An appropriate three-dimensional model for evaluation of anticancer drug sensitivity

Abstract The extracellular polysaccharide hyaluronan (HA) controls cell migration, differentiation and proliferation, and contributes to the invasiveness of human cancers. In order to investigate the sensitivity of cancer cells to antimitotic agents, we developed a cross-linked HA hydrogel, a three-dimensional matrix in which cells can invade and grow. We have Read more…

A biomimetic hydrogel functionalized with adipose ECM components as a microenvironment for the 3D culture of human and murine adipocytes

Abstract The lack of relevant in vitro models for adipose tissue makes necessary the development of a more physiological environment providing spatial and chemical cues for the effective maturation of adipocytes. We developed a biofunctionalized hydrogel with components of adipose extracellular matrix: collagen I, collagen VI, and the cell binding Read more…

Evaluation by quantitative image analysis of anticancer drug activity on multicellular spheroids grown in 3D matrices

Abstract Pharmacological evaluation of anticancer drugs using 3D in vitro models provides invaluable information for predicting in vivo activity. Artificial matrices are currently available that scale up and increase the power of such 3D models. The aim of the present study was to propose an efficient and robust imaging and Read more…
