Associations of Osteoblasts with chemical compounds

  • Osf2/Cbfa1 expression is initiated in the mesenchymal condensations of the developing skeleton, is strictly restricted to cells of the osteoblast lineage thereafter, and is regulated by BMP7 and vitamin D3 [25].
  • Here, we demonstrate that HSCs expressing the receptor tyrosine kinase Tie2 are quiescent and antiapoptotic, and comprise a side-population (SP) of HSCs, which adhere to osteoblasts (OBs) in the BM niche [26].
  • Endothelin-1, more commonly known as a potent vasoconstrictor, is a normal ejaculate protein that also stimulates osteoblasts [27].
  • Impaired osteoblast function due to E deficiency, aging, or both also contributes to the slow phase of bone loss [28].
  • Progesterone appears to act directly on bone by engaging an osteoblast receptor or indirectly through competition for a glucocorticoid osteoblast receptor [11].
 

Gene context of Osteoblasts

  • Osf2/Cbfa1: a transcriptional activator of osteoblast differentiation [25].
  • Here we show that Tob, a member of the emerging family of antiproliferative proteins, is a negative regulator of BMP/Smad signaling in osteoblasts [29].
  • We demonstrate LRP5 expression by osteoblasts in situ and show that LRP5 can transduce Wnt signaling in vitro via the canonical pathway [30].
  • This reduction is caused by severe impairment of bone formation, suggesting that NFAT transcription factors also have an important role in the transcriptional program of osteoblasts [31].
  • This increase is caused by excessive osteoblast differentiation, wherein Stat1 function is independent of IFN signaling [32].
