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.
The epidermal growth factor (EGF) receptor/ligand system stimulates multiple pathways of signal transduction, and is activated by various extracellular stimuli and inter-receptor crosstalk signaling. Aberrant activation of EGF receptor (EGFR) signaling is ...
An asymmetric cell division (ACD) is defined as a division that gives rise to two daughter cells with different fates. It is the most common type of division during development. Analogous to Drosophila neuroblasts, proteins involved in ACD such as Insc and ...
While cell sorting usually relies on cell-surface protein markers, molecular beacons (MBs) offer the potential to sort cells based on the presence of any expressed mRNA and in principle could be extremely useful to sort rare cell populations from primary i ...
The thymus is a primary lymphoid organ where bone marrow derived T-cell progenitors come in contact with a unique microenvironment able to sustain their maturation into functional T-cells. This fundamental immunological function of the thymus is supported ...
PCP proteins are restricted to progenitor cells in the embryonic pancreas. The PCP core components Celsr2/3 control endocrine cell differentiation. This effect is mediated by the JNK pathway ...
The intestine represents the most vigorously renewing, adult epithelial tissue that makes maintenance of its homeostasis a delicate balance between proliferation, cell cycle arrest, migration, differentiation, and cell death. These processes are precisely ...
The pancreas plays a central role in metabolism. The exocrine pancreas, composed of ductal and acinar cells, secretes and delivers digestive enzymes into the duodenum where they contribute to food digestion. The endocrine pancreas, constituted by the islet ...
The formation and maintenance of boundaries between neighbouring groups of embryonic cells is vital for development because groups of cells with distinct functions must often be kept physically separated. Furthermore, because cells at the boundary often ta ...
BACKGROUND & AIMS: Ablation of Notch signaling within the intestinal epithelium results in loss of proliferating crypt progenitors, due to their conversion into post-mitotic secretory cells. We aimed to confirm that Notch was active in stem cells (SC), inv ...
ABSTRACT: BACKGROUND: Gut homeostasis is central to whole organism health, and its disruption is associated with a broad range of pathologies. Following damage, complex physiological events are required in the gut to maintain proper homeostasis. Previously ...
