Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Nowadays, there are still several unmet medical needs in the field of orthopaedic and trauma surgery leading to the incentive of finding alternative and innovative clinical therapeutics for the treatment of bone regeneration. For example, the entrapment of ...
For tissue engineering, several cell types and tissues have been proposed as starting material. Allogenic skin products available for therapeutic usage are mostly developed with cell culture and with foreskin tissue of young individuals. Fetal skin cells o ...
Myofibroblasts are reparative connective tissue cells that contribute to the reconstruction of injured tissue by secreting new extracellular matrix and by exerting high contractile force. Deregulation of these activities results in tissue contracture and d ...
A major challenge for therapeutic delivery of angiogenic agents such as vascular endothelial growth factor (VEGF) is to achieve sustained, low dose signaling leading to durable neovessel formation. To this end, we recently created a variant of VEGF(121), T ...
The lack of angiogenesis in ischemic tissues is a major health problem and many studies aim to explore strategies to locally increase blood perfusion. Our approach is to use covalently modified fibrin-based hydrogels as a matrix that induces endothelial ce ...
Cripto is a glycosylphosphatidylinositol (GPI)-anchored co-receptor of Nodal and several other transforming growth factor-beta (TGF-beta) family ligands. It contains an epidermal growth factor (EGF)-like motif and a Cripto-FRL1-Cryptic (CFC) domain, which ...
In this thesis, the potential use of fetal bone cells for tissue engineering was evaluated. At first, fetal bone cells were characterized in vitro regarding their proliferation rate, the induction of their osteoblastic phenotype, and their antigenicity. Th ...
We studied the mechanisms underlying the severely impaired wound healing associated with human leukocyte-adhesion deficiency syndrome-1 (LAD1) using a murine disease model. In CD18(-/-) mice, healing of full-thickness wounds was severely delayed during gra ...
Fibroblast-to-myofibroblast differentiation - a key event in the development of fibrocontractive diseases and in wound granulation tissue contraction - is hallmarked by the formation of stress fibers and the neo-expression of alpha-smooth muscle actin. Inc ...
The conjunctive presence of mechanical stress and active transforming growth factor beta1 (TGF-beta1) is essential to convert fibroblasts into contractile myofibroblasts, which cause tissue contractures in fibrotic diseases. Using cultured myofibroblasts a ...
