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.
Bone marrow transplantation is a well-established medical procedure for the treatment of various hematologic diseases. However, the relatively low number of hematopoietic stem cells (HSCs) that can be harvested, especially from umbilical cord blood, limits ...
Hematopoietic stem cells (HSCs) are responsible for the continuous production of all blood cells. This unique ability has made it possible to successfully use HSCs in the clinical setting to remedy various blood disorders. However, despite six decades of r ...
Although stem cells hold tremendous potential for clinical applications, their in vitro manipulation remains very challenging. In vivo, stem cells reside in intricate 3D microenvironments, termed niche, in which many local and systemic extrinsic factors ar ...
Signaling centers, localized groups of cells that secrete morphogens, play a key role in early development and organogenesis by orchestrating spatial cell fate patterning. Here we present a microfluidic approach that exposes human pluripotent stem cell (hP ...
Developmental Hedgehog (Hh) signaling is found deregulated in a broad spectrum of human malignancies and, thus, is an attractive target for cancer therapy. Currently available Hh inhibitors have shown the rapid occurrence of drug resistance, due to altered ...
The application of stem cells in drug screening and regenerative therapy has led to important advances in basic biology and biomedicine. Such strategies require high cell numbers and the efficient maturation into faithful functional organ or tissue units. ...
Stem cells play a key role in a wide range of biological processes, in large part due to their ability to self-renew or differentiate into specialized cell types in response to various biological cues. In vivo, stem cells reside in a complex microenvironme ...
Hematopoietic stem cells (HSC) are responsible for the life-long maintenance of our blood system. Their long-term capacity to both self-renew and differentiate and the ability to efficiently âhomeâ to their bone marrow niches when injected in the blood ...
Hierarchical organization of tissues relies on stem cells, which either self-renew or produce committed progenitors predestined for lineage differentiation. Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify ...
Acute myelogenous leukemia (AML) is initiated and maintained by leukemia stem cells (LSC). LSCs are therapy-resistant, cause relapse, and represent a major obstacle for the cure of AML. Resistance to therapy is often mediated by aberrant tyrosine kinase (T ...
