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…

Extracellular matrix modifications are involved in cancer initiation, progression and propagation

The extracellular matrix (ECM) is the non-cellular component of tissue. Its is mainly composed of structural and adhesion molecules, such as hyaluronic acid, collagene, proteoglycans, fibronectin, elastin, although its specific composition and structure vary between different tissues. It is a dynamic structure, which is involved not only in the cell 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…

Parliament urges the EU to accelerate the transition to a research system that does not use animals : we support it!

Earlier this month, the European parliament has voted for accelerating the limitation (end?) of animal testing for research, regulatory and education purposes. As a reminder, the testing ban on finished cosmetic products applies since 11 September 2004 and the testing ban on ingredients (or combination of ingredients) applies since 11 Read more…
