TLDR
It is shown that MCAM/CD146-expressing, subendothelial cells in human BM stroma are capable of transferring, upon transplantation, the HME to heterotopic sites, coincident with the establishment of identical subendOThelial cells within a miniature bone organ.About:

Clec11a/osteolectin is an osteogenic growth factor that promotes the maintenance of the adult skeleton
Rui Yue,Bo Shen,Sean J. Morrison +2 more
TL;DR: Recombinant human Clec11a promoted osteogenesis by human bone marrow stromal cells in culture and increased bone mass in osteoporotic mice in vivo and is proposed to call this factor Osteolectin.

Mesenchymal Stromal Cell Migration: Possibilities to Improve Cellular Therapy
TL;DR: Understanding MSC migration will offer perspectives to modulate the expansion protocols to obtain cells that maintain migration and homing capacities and improve MSC-based therapy.

Interleukin-1 beta and tumor necrosis factor alpha inhibit migration activity of chondrogenic progenitor cells from non-fibrillated osteoarthritic cartilage
TL;DR: Results indicate that traumatized cartilage releases chemoattractive factors for CPC but IL-1β and TNF-α inhibit their migratory activity which might contribute to the low regenerative potential of cartilage in vivo.

Skeletal stem cells: phenotype, biology and environmental niches informing tissue regeneration.
TL;DR: This review will examine skeletal stem cell biology, the advances in the understanding of the skeletal and perivascular niche and interactions therein and the opportunities to harness that knowledge for musculoskeletal regeneration.

Skeletal (stromal) stem cells: An update on intracellular signaling pathways controlling osteoblast differentiation
Basem M. Abdallah,Abbas Jafari,Abbas Jafari,Walid Zaher,Walid Zaher,Weimin Qiu,Moustapha Kassem,Moustapha Kassem,Moustapha Kassem +8 more
TL;DR: The functions and the molecular mechanisms of action on osteoblast differentiation and bone formation are discussed; of a number of recently identified regulatory molecules: the non-canonical Notch signaling molecule Delta-like 1/preadipocyte factor 1 (Dlk1/Pref-1), the Wnt co-receptor Lrp5 and intracellular kinases.

Exploration, normalization, and summaries of high density oligonucleotide array probe level data
Rafael A. Irizarry,Bridget G. Hobbs,Francois Collin,Yasmin Beazer-Barclay,Kristen J. Antonellis,Uwe Scherf,Terence P. Speed +6 more
TL;DR: There is no obvious downside to using RMA and attaching a standard error (SE) to this quantity using a linear model which removes probe-specific affinities, and the exploratory data analyses of the probe level data motivate a new summary measure that is a robust multi-array average (RMA) of background-adjusted, normalized, and log-transformed PM values.

Mesenchymal stem cells
TL;DR: The study of mesenchymal stem cells, whether isolated from embryos or adults, provides the basis for the emergence of a new therapeutic technology of self‐cell repair.
Journal ArticleDOI
Mesenchymal Stem Cells
TL;DR: The bone marrow contains multipotent MSC, which can be easily isolated and cultured in vitro, and the possibility of their clinical use in cell and gene therapy is analyzed.

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

Mark J. Kiel,Ömer H. Yilmaz,Toshihide Iwashita,Osman H. Yilmaz,Cox Terhorst,Sean J. Morrison +5 more
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.
