Background and Objective: Mobilization of Hematopoietic Stem Cells (HSCs) for transplantation and the importance of -adrenergic signals in induction of this process have been well investigated. However, little is known about the role of -adrenergic signals in mobilization of HSCs and factors influenced by these signals. The Chemokine Stromal Derived Factor -1 (SDF-1) which is expressed by hum...
Hematopoietic cell clusters in the aorta of vertebrate embryos play a pivotal role in the formation of the adult blood system. Despite their importance, hematopoietic clusters have not been systematically quantitated or mapped because of technical limitations posed by the opaqueness of whole mouse embryos. Here, we combine an approach to make whole mouse embryos transparent, with multicolor mar...
Embryonal stem cells have been shown to differentiate in vitro into all hematopoietic lineages. This has been used successfully as one approach to the study of genetic events occurring during haematopoiesis. However, studies on the commitment of mesodermal precursors to the hematopoietic lineage have been limited due to the inability to define a system in which embryonal stem (ES) cells will gi...
