TLDR
Angiogenic models are developed to demonstrate that EC-derived angiocrine growth factors support in vitro self-renewal and in vivo repopulation of authentic LT-HSCs, and establish an instructive vascular niche for clinical-scale expansion of LT- HSCs and a cellular platform to identify stem cell-active trophogens.About:

The bone marrow niche for haematopoietic stem cells
TL;DR: The haematopoietic stem cell niche remains incompletely defined and beset by competing models, and outstanding questions concern the cellular complexity of the niche, the role of the endosteum and functional heterogeneity among perivascular microenvironments.
Journal ArticleDOI
Endothelial and perivascular cells maintain haematopoietic stem cells
TL;DR: HSCs reside in a perivascular niche in which multiple cell types express factors that promote HSC maintenance, and were depleted from bone marrow when Scf was deleted from endothelial cells or leptin receptor (Lepr)-expressing periv vascular stromal cells.

Haematopoietic stem cells and early lymphoid progenitors occupy distinct bone marrow niches

TL;DR: Assessment of the physiological sources of the chemokine CXCL12 for HSC and restricted progenitor maintenance shows that Cxcl12 was primarily expressed by perivascular stromal cells and, at lower levels, by endothelial cells, osteoblasts and some haematopoietic cells.

The perivascular niche regulates breast tumour dormancy

TL;DR: It is revealed that stable microvasculature constitutes a dormant niche, whereas sprouting neovasculature sparks micrometastatic outgrowth, which is a surprising result in dormancy models and in zebrafish.

TL;DR: Osteoblastic cells are a regulatory component of the haematopoietic stem cell niche in vivo that influences stem cell function through Notch activation.

SLAM Family Receptors Distinguish Hematopoietic Stem and Progenitor Cells and Reveal Endothelial Niches for Stem Cells

TL;DR: This work compared the gene expression profiles of highly purified HSCs and non-self-renewing multipotent hematopoietic progenitors and found that both groups occupied multiple niches, including sinusoidal endothelium in diverse tissues.

TL;DR: It is concluded that SNO cells lining the bone surface function as a key component of the niche to support HSCs, and that BMP signalling through BMPRIA controls the number of H SCs by regulating niche size.

Wnt proteins are lipid-modified and can act as stem cell growth factors

TL;DR: This work isolated active Wnt molecules, including the product of the mouse Wnt3a gene, and found the proteins to be palmitoylated on a conserved cysteine, indicating that the lipid is important for signalling.

Tie2/Angiopoietin-1 Signaling Regulates Hematopoietic Stem Cell Quiescence in the Bone Marrow Niche
Fumio Arai,Atsushi Hirao,Masako Ohmura,Hidetaka Sato,Sahoko Matsuoka,Keiyo Takubo,Keisuke Ito,Gou Young Koh,Toshio Suda +8 more
TL;DR: It is demonstrated that HSCs expressing the receptor tyrosine kinase Tie2 are quiescent and antiapoptotic, and comprise a side-population (SP) of H SCs, which adhere to osteoblasts (OBs) in the BM niche.
