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.
During tissue development, cells are able to form different layers and to self organize. At the moment, there are two principal hypotheses that try to explain cell sorting. The so called differential adhesion hypothesis (DAH) posits that cells organize acc ...
The epithelial-mesenchymal transition (EMT) is a key developmental program that is often activated during cancer invasion and metastasis. We here report that the induction of an EMT in immortalized human mammary epithelial cells (HMLEs) results in the acqu ...
As primary lymphoid organ, the thymus provides the essential environment for maturation and selection of functional T lymphocytes. Thymic epithelial (TE) cells derive from the endoderm, and more specifically, from the third pharyngeal pouch. The thymic epi ...
The formation of scar tissue due to dedifferentiation of smooth muscle cells (SMCs) is one of the major issues faced when engineering bladder tissue. Furthermore, cell sources for regenerating the SMC layer are also limiting. Here we explore if human mesen ...
This unit describes a protocol for the isolation of cells from murine embryonic stem cells with hematopoietic stem cell activity, defined by the ability to reconstitute, long term, multiple lineages of the hematopoietic system of lethally irradiated mice. ...
The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty- five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal trans ...
Embryonic stem (ES) cells represent a unique cellular model to recapitulate in vitro early steps of embryonic development and an unlimited cellular source in therapy for many diseases, as well as targets for drug discovery and toxicology screens. Although ...
Hair follicles are cutaneous structures characteristic of mammals. These sensitive organs cycle and contain multipotent epithelial stem cells which are implicated in hair growth and hair cycle. A single whisker follicle of the rat hosts up to 1500 stem cel ...
The epidermis and its appendages protect our body from environmental hazards. Cells generated in the basal layer continuously replace the terminally differentiated keratinocytes that are shed off the epidermal surface. Long-term renewal depends on specific ...
Continuous turnover of epithelia is ensured by the extensive self-renewal capacity of tissue-specific stem cells. Similarly, epithelial tumour maintenance relies on cancer stem cells (CSCs), which co-opt stem cell properties. For most tumours, the cellular ...
