Novel determinants of the hematopoietic microenvironment in development and homeostasis

Olaia Maria Naveiras Torres-Quiroga

The promise of regenerative medicine depends on succeeding at generating sufficient amounts of functional, transplantable tissue by reliably differentiating pluripotent stem cells through the paths of ontogeny, or by efficiently expanding adult stem cells ...

Prospective identification of hematopoietic and neural stem/progenitor cells using transgenic and lentiviral based approaches

Didier Surdez

Adult stem cells represent only a minor proportion of a given tissue and are difficult to amplify in vitro without affecting their biological properties. To circumvent this problem, we used a transgenic/lentiviral based approach to isolate and characterize ...

Epithelial stem cells and mechanical signal transduction

Vincent Bernard Cattin

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 Notch signaling pathway is an essential cell-cell interaction mechanism, which regulates processes such as cell proliferation, cell fate decisions, differentiation or stem cell maintenance. Pigmentation in mammals is provided by melanocytes, which are ...

Over-expression of alpha-synuclein in human neural progenitors leads to specific changes in fate and differentiation

Patrick Aebischer, Bernard Schneider

Missense mutations and extra copies of the alpha-Synuclein gene result in Parkinson disease (PD). Human stem and progenitor cells can be expanded from embryonic tissues and provide a source of non-transformed neural cells to explore the effects of these pa ...

Given their accessibility, multipotent skin-derived cells might be useful for future cell replacement therapies. We describe the isolation of multipotent stem cell-like cells from the adult trunk skin of mice and humans that express the neural crest stem c ...

Essential role of endothelial Notch1 in angiogenesis

Freddy Radtke

BACKGROUND: Notch signaling influences binary cell fate decisions in a variety of tissues. The Notch1 receptor is widely expressed during embryogenesis and is essential for embryonic development. Loss of global Notch1 function results in early embryonic le ...

Signals from lateral plate mesoderm instruct endoderm toward a pancreatic fate

Anne Grapin-Botton, Mithlesh Kumar

During embryonic development, organs arise along the gut tube as a series of buds in a stereotyped anterior-posterior (A-P) pattern. Using chick-quail chimeras and in vitro tissue recombination, we studied the interactions governing the. induction and main ...

Notch1 is required for neuronal and glial differentiation in the cerebellum

Freddy Radtke, Michel Aguet

The mechanisms that guide progenitor cell fate and differentiation in the vertebrate central nervous system (CNS) are poorly understood. Gain-of-function experiments suggest that Notch signaling is involved in the early stages of mammalian neurogenesis. On ...

Circletail, a new mouse mutant with severe neural tube defects: chromosomal localization and interaction with the loop-tail mutation

Friedrich Beermann

Circletail (Crc) is a new mouse mutant that exhibits a severe form of neural tube defect, craniorachischisis, in which almost the entire neural tube fails to close. This phenotype is seen in very few other mutants, the best characterized of which is loop-t ...
