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.
How cells break symmetry and organize activity at their edges to move directionally is a fundamental question in cell biology. Physical models of cell motility commonly incorporate gradients of regulatory proteins and/or feedback from the motion itself to ...
Stem cell therapies hold tremendous potential for tissue and organ regeneration. Yet, there remains significant need for better ex vivo culture and manipulation methods. On the one hand, many tissue-specific stem cells cannot be propagated without causing ...
Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. This unique characteristic makes them an ideal candidate for cell-based therapies to treat various hematological malignancies. Their extensive use in the cl ...
Infections are one of the most common complications in burn injuries. In severe burns, the wound surface is optimal for microbial proliferation as the exudate is a protein rich environment. Autograft and cultured grafts are the main treatments used nowaday ...
Bone fracture healing problems, because of the loss of tissue regeneration, can affect many old or multi-pathologic patients around the world. Among the therapeutic strategies, bone substitutes, such as poly-(L-lactitve acid) with 5% wt. % ß-tricalcium pho ...
Juxtacrine or contact-dependent signaling is a major form of cell communication in multicellular organisms. The involved cell-cell and cell-extracellular-matrix (ECM) interactions are crucial for the organization and maintenance of tissue architecture and ...
Image-based identification of cultured stem cells and noninvasive evaluation of their proliferative capacity advance cell therapy and stem cell research. Here we demonstrate that human keratinocyte stem cells can be identified in situ by analyzing cell mot ...
Fetal therapies have become available for a restricted number of life-threatening clinical conditions. Harnessing tissue engineering for prenatal applications has not been widely pursued even though isolating cells from fetal and extraembryonic tissues has ...
Dorsal root ganglia (DRG) neurons, located in the intervertebral foramina of the spinal column, can be used to create an in vitro system facilitating the study of nerve regeneration and myelination. The glial cells of the peripheral nervous system, Schwann ...
One of the most important steps in tumor progression involves the transformation from a differentiated epithelial phenotype to an aggressive, highly motile phenotype, where tumor cells invade neighboring tissues. Invasion can occur either by isolated mesen ...
