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. ...
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 present invention provides methods for inducing differentiation of a stem cell, such as an embryonic stem cell, into a hematopoietic stem cell, by expressing a cdx gene and/or a hox gene. The method is useful for generating expanded populations of hema ...
In recent years a substantial body of evidence has accumulated to support the notion that signaling pathways known to be important during embryonic development play important roles in regulating self-renewing tissues. Moreover, the same pathways are often ...
Adult stem cells are essential to maintain regenerative tissues such as skin epidermis, gastrointestinal mucosa or the hematopoietic system. Recent studies in mice suggest that the transcription factor and oncoprotein c-Myc has unexpected functions during ...
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 ...
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 ...
Gain-of-function experiments have demonstrated the potential of Notch signals to expand primitive hematopoietic progenitors, but whether Notch physiologically regulates hematopoietic stem cell (HSC) homeostasis in vivo is unclear. To answer this question, ...
Adult stem cells hold many promises for future clinical applications and regenerative medicine. The haematopoietic stem cell (HSC) is the best-characterized somatic stem cell so far, but in vitro expansion has been unsuccessful, limiting the future therape ...
Bone marrow-derived cells include haematopoietic cell lineages and the recently described endothelial progenitor cells (EPCs). It has been recently emphasised that these marrow-derived cells contribute to tumour angiogenesis, and different mechanisms have ...
