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.
Traditional cell cultures have long been fundamental to biological research, offering an alternative to animal models burdened by ethical constraints and procedural intricacies, often lacking relevance to human physiology and disease. Moreover, their inabi ...
Adipose tissue is a key metabolic and highly-dynamic organ whose dysregulation may cause clinical conditions of concern such as obesity and lipodystrophy. Its function varies based on the anatomy, in fact, visceral adipose tissue expansion carries a greate ...
Fatty acid beta-oxidation (FAO), the breakdown of lipids, is a metabolic pathway used by various stem cells. FAO levels are generally high during quiescence and downregulated with proliferation. The endogenous metabolite malonyl-CoA modulates lipid metabol ...
BACKGROUND & AIMS: Colonic stem cells are essential for producing the mucosal lining, which in turn protects stem cells from insult by luminal factors. Discovery of genetic and biochemical events that control stem cell proliferation and differentiation can ...
BACKGROUND & AIMS: Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nu ...
Bone marrow transplantation is a well-established medical procedure for the treatment of various hematologic diseases. However, the relatively low number of hematopoietic stem cells (HSCs) that can be harvested, especially from umbilical cord blood, limits ...
The gastrointestinal tract has recently come to the forefront of multiple research fields. It is now recognized as a major source of signals modulating food intake, insulin secretion and energy balance. It is also a key player in immunity and, through its ...
Intestinal infection triggers potent immune responses to combat pathogens and concomitantly drives epithelial renewal to maintain barrier integrity. Current models propose that epithelial renewal is primarily driven by damage caused by reactive oxygen spec ...
In spite of decades of research, no feasible method for obtaining sufficient numbers of uncommitted muscle stem cells (MuSCs) for therapy of degenerative muscle diseases exists. One of the most fundamental problems associated with stem cell therapy of musc ...
Hematopoietic stem cells (HSCs) are responsible for the continuous production of all blood cells. This unique ability has made it possible to successfully use HSCs in the clinical setting to remedy various blood disorders. However, despite six decades of r ...
