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.
Embryonic stem (ES) cells have the capacity to give rise to all cell types of the adult organism and can be used as a model to study early cell fate decisions as they closely recapitulate in vivo events. The M and G1 phases have been suggested to be the ke ...
The speed of stem cell differentiation has to be properly coupled with self-renewal, both under basal conditions for tissue maintenance and during regeneration for tissue repair. Using the Drosophila midgut model, we analyze at the cellular and molecular l ...
In this work we have evaluated the capacity of bone morphogenetic protein-2 (BMP-2) and fibrin-binding platelet-derived growth factor-BB (PDGF-BB) to support cell growth and induce bone regeneration using two different imaging technologies to improve the u ...
Articular cartilage regeneration poses particularly tough challenges for implementing cell-based therapies. Many cell types have been investigated looking for a balanced combination of responsiveness and stability, yet techniques are still far from definin ...
The tumor suppressor protein p53 plays important roles in DNA damage repair, cell cycle arrest and apoptosis. Due to its critical functions, the level of p53 is tightly regulated by a negative feedback mechanism to increase its tolerance towards fluctuatio ...
Typically, immune responses control the pathogen, while repair and stress pathways limit damage caused by pathogenesis. The relative contribution of damage to the outcome of pathogenesis and the mechanistic links between the immune and repair pathways are ...
Cells respond to stress by coordinating proliferative and metabolic pathways. Starvation restricts cell proliferative (glycolytic) and activates energy productive (oxidative) pathways. Conversely, cell growth and proliferation require increased glycolytic ...
Conducting tissue healing and regeneration through biomaterials and morphogens is still an unrealized goal. Understand the multiple roles of the extracellular matrix (ECM) is indeed essential for the design of successful regenerative medicine strategies. D ...
Bioactive hydrogels formed by Michael-type addition reactions of end-functionalized poly(ethylene glycol) macromers with cysteine-containing peptides have been described as extracellular matrix mimetics and tissue engineering scaffolds. Although these mate ...
Currently, both congenital abnormalities and developmental problems of the bladder in children, and other dysfunctions in adults, require reconstructive surgery. Such correction involves transplant action of native tissues (such as gastrointestinal segment ...
