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.
Stem cell use in bladder tissue engineering is a recently addressed area of investigation that has generated excitement as a novel way to restore and regenerate lost or damaged urinary bladder tissue. The remodelling of smooth muscle plays a significant ro ...
The nuclear protein c-Myc is one of the most potent proto-oncogenes described. Its expression is found to be deregulated in more than 50 percent of human cancers, where it has been shown to control a number of biological processes including driving prolife ...
Transforming Growth Factor beta (TGFβ) signaling plays an important role in a variety of cellular processes during embryonic development, adult tissue homeostasis and cancer. TGFβI ligand is a potent inhibitor of early hematopoietic progenitor [1] cells in ...
The promise of regenerative medicine depends on succeeding at generating sufficient amounts of functional, transplantable tissue by reliably differentiating pluripotent stem cells through the paths of ontogeny, or by efficiently expanding adult stem cells ...
Mesenchymal stem cells (MSC) are a population of multipotent cells that can differentiate into various lineages such as fibroblast, osteoblast, chondrocyte and adipocyte and can be maintained over extended periods in vitro. They are also known to have a su ...
Muscle degenerative disorders, such as Duchenne muscular dystrophy, have a profound impact on the quality of life and survival of patients. Transplantation of myoblasts to restore muscle function has been discouraging since these cells die and don't migrat ...
Surface antigens on hematopoietic stem cells (HSCs) enable prospective isolation and characterization. Here, we compare the cell-surface phenotype of hematopoietic repopulating cells from murine yolk sac, aorta-gonad-mesonephros, placenta, fetal liver, and ...
In the domain of regenerative medicine research there are many fronts aimed at increasing our understanding of induced pluripotent, embryonic and adult stem cells. Recently a new front has appeared, stem cell niches, the microenvironment that is a crucial ...
Human embryonic stem (hES) cells can self-renew in culture and differentiate into cells of all three germ layers. Identification of regulators of the self-renewal versus differentiation decisions in hES cells will facilitate manipulation of these cells. Se ...
We describe herein some immunological properties of human fetal bone cells recently tested for bone tissue engineering applications. Adult mesenchymal stem cells and adult osteoblasts were included in the study for comparison. Surface markers involved in b ...
