Graph Chatbot
Chattez avec Graph Search
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 canonical Wnt signaling pathway plays key roles in stem-cell maintenance, progenitor cell expansion, and lineage decisions. Transcriptional responses induced by Wnt depend on the association of either beta-catenin or gamma-catenin with lymphoid enhance ...
Upon encounter of viral Ags in an inflammatory environment, dendritic cells up-regulate costimulatory molecules and the chemokine receptor CCR7, with the latter being pivotal for their migration to the lymph node. By utilizing mice deficient in CCR7, we ha ...
The invention relates to a device for dispensing droplets comprising a first channel (8, 10), known as the main channel, for circulating a first liquid flow, a second channel (12, 13) for circulating fluid, forming an intersection area (27) with the first ...
This paper reports on a novel method for on-chip continuous separation of divid- ing and non-dividing cells based on differences in their dielectric properties. By means of two opposite dielectrophoretic force fields at multiple frequencies, the two popula ...
Angiogenic tumor vessels are promising targets for the activity and the selective delivery of cancer therapeutics. The bone marrow contributes different cell types to the tumor stroma, including hematopoietic cells and, as recently suggested, vascular endo ...
A PEG-based polymer matrix is developed within which biol. macromols. and living mammalian cells could be easily dispersed. Constraints placed upon such a matrix by a desire that it be generally processable in the presence of biol. macromols. and living ce ...
B cells undergo a complex series of maturation and selection steps in the bone marrow and spleen during differentiation into mature immune effector cells. The tumor necrosis factor (TNF) family member B cell activating factor of the TNF family (BAFF) (BLyS ...
The development of T cells from pluripotent stem cells involves a coordinated series of lineage-commitment steps. Common lymphoid precursors in the fetal liver or adult bone marrow must first choose between a T, B or NK cell fate. Committed T cell precurso ...
BACKGROUND: Autologous transplantation is an attractive approach to treat some neurological diseases. A major obstacle is the capacity to produce cells for transplantation at the appropriate time. We describe a cryopreservation procedure for adult human br ...
A motion planning algorithm for automatic path computation for an autonomous virtual human in an environment of obstacles is presented. The environment is discretized and an optimum path in terms of number of cells is computed using A* search technique ...
