Impairment of extracellular matrix remodeling is observed in the tumor microenvironment or fibrosis and results in excessive collagen production and/or decreased degradation by matrix metalloproteinases (MMPs). Thanks to their local application and transient effects, physical stimuli appear as attractive tools to remodel the extracellular matrix. We assessed the potential of pulsed electric field technology, classically applied to drug delivery, to induce collagen remodeling at the tissue scale. A sophisticated in vitro tissue-engineered human dermal substitute was used to show that microsecond and millisecond pulsed electric fields induced (i) a rapid modulation (4 hours after electrostimulation) of mRNA genes composing the matrisome, particularly a downregulation of procollagens and extracellular matrix maturation enzymes such as transglutaminase 2 and lysyl oxidase like; (ii) a transient decrease in procollagens production and hydroxyproline tissue content within a week after electrostimulation; (iii) a long-lasting ROS-dependent overactivation of matrix metalloproteinases for at least 48 hours; and (iv) a downregulation of TGFβ1. These observations underpin that pulsed electric fields, a technology already approved for clinical use combined with anticancer agents, are particularly promising to provide local and effective treatment of abnormal extracellular matrix.

Heparan-mimetics: Potential agents of tissue regeneration for bone andperiodontal therapies

Heparan sulfate glycosaminoglycans are key players of tissue repair and can be regarded as useful compounds for regenerative medicines. Unfortunately, their therapeutic uses face many technical, industrial, and regulatory hurdles due to their animal origin. So, some non-animal sulfated polysaccharides mimic heparan sulfate properties and offer interesting solutions to replace them. Among them, dextran derivatives, seaweed polysaccharides, or marine bacterial polysaccharides are the best known and have demonstrated their pro-regenerative capabilities
by promoting both extracellular matrix structuring and angiogenesis and limiting degenerative processes such as inflammatory cell migration or tissue proteolysis. These polysaccharides have also shown their ability to specifically promote osteoblastic differentiation and bone wound healing. Furthermore, recent works shows that heparan-mimetics can be used as an additive to improve the cytocompatibility of bone substitutes commonly used in periodontal surgery. The use of these polysaccharides can be regarded as a clever approach to improve the
biointegration of bone substitutes.

Publication eBook « Matricellular Receptors as Potential Targets in Anti-Cancer Therapeutic Strategies »

couverture-ebook-1Hervé Emonard, Stéphane Dedieu et Laurent Duca ont le plaisir de vous annoncer la publication chez Frontiers in Pharmacology et la mise en ligne d’un numéro spécial intitulé « Matricellular Receptors as Potential Targets in Anti-Cancer Therapeutic Strategies ».

Ce livre, composé d’articles de revue et de recherches originales, présente les données récentes obtenues dans l’étude des récepteurs membranaires dont les rapports, directs ou indirects, avec la matrice extracellulaire modulent le comportement cellulaire. Il fait également le point sur l’identification de ces récepteurs « matricellulaires » comme cibles thérapeutiques dans le contexte de pathologie tumorale.
De nombreux membres de la SFBMEc ont contribué à sa réalisation.

La version electronique de cet ouvrage « Matricellular Receptors as Potential Targets in Anti-Cancer Therapeutic Strategies » est consultable/téléchargeable ici.

Hervé Emonard, Stéphane Dedieu and Laurent Duca are pleased to announce the publication by Frontiers in Pharmacology of a special issue entitled « Matricellular Receptors as Potential Targets in Anti-Cancer Therapeutic Strategies ».

This book, composed of bibliographic reviews and original reports, present recent data on the cell membrane receptors which mediate signaling from the extracellular environment to modulate cell behavior. It also highlights the identification of these « matricellular » receptors as therapeutic targets in the context of tumor pathology.
Many members of the SFBMEc contributed to its realization.

• The matrisome is defined as the ensemble of 1000 + genes encoding ECM and ECM-associated proteins.

• Bioinformatic and experimental approaches to study the ECM/matrisome are discussed.

• We introduce a novel website and database MatrisomeDB to centralize resources on the matrisome.

• We present a draft of an ECM atlas compiling proteomics data on the ECM of 14 different tissues and tumors.

• “Omics” data provide novel insights into ECM functions in development, homeostasis and disease.
