    ..While live imaging and FACS analysis allows enumeration of total or site-specific HSPCs, the cell culture assay provides the unique opportunity to test the functional potential of isolated HSPCs, similar to those employed in mammals. ..
  4. Goessling W, North T. EnaBILEing Growth in the Fetal Liver. Cell Stem Cell. 2016;18:427-8 pubmed publisher
    ..Sigurdsson et al. (2016) provide justification for transient fetal liver residence, where select bile acid composition, derived from mother and embryo, provides a protective environment, enabling rapid stem cell expansion. ..

    ..Our data establish that embryonic HSC production responds to physiologic stress via CNS-derived serotonin synthesis and central feedback regulation to control HSC numbers. ..

    ..Together, these data suggest that yolk-derived E2 sets the ventral boundary of hemogenic vascular niche specification by antagonizing the dorsal-ventral regulatory limits of VEGF. ..

    ..These findings highlight a direct impact of inefficient vitamin D synthesis on cell fate commitment and maturation in Hh-regulated tissues, which may have implications beyond hemogenic endothelium specification. ..

    ..Together, these findings define a Hif1α-regulated signaling axis mediated through PBFGB/PDGFRβ and IL-6/IL-6R that acts to control embryonic HSPC production. ..
