Osteoblast: A cell under compression
Bio-Medical Materials and Engineering, 2008Bone tissue remodeling results from the coordinated and balanced activities of osteoblasts and osteoclasts. Osteoblast function is intimately linked to osteoclast activity via the osteoblast production of cytokines, growth factors and prostaglandins (PGs). The production of some of these factors is controlled by mechanical strains.

Cell-to-Cell Communication of Osteoblasts
Journal of Dental Research, 1979Osteoblasts were investigated by two methods, electrical conductance and dye injection. Current injection into one cell caused a change in the recorded transmembrane potential of a second cell, indicating high conductance pathways between the two cells. Dyes injected into a single osteoblast were transmitted to numerous surrounding cells.

Pinacidil stimulates osteoblast function in osteoblastic MC3T3-E1 cells
Immunopharmacology and Immunotoxicology, 2013This study examined the effect of pinacidil, a nonselective adenosine triphosphate-sensitive potassium channel opener, on the function of osteoblastic MC3T3-E1 cells. Pinacidil caused a significant elevation of collagen synthesis, alkaline phosphatase activity, osteocalcin synthesis and mineralization in the cells (p

Regulation of Osteoblast Differentiation by Slit2 in Osteoblastic Cells
Cells Tissues Organs, 2008<i>Background/Aims:</i> There is an urgent need to identify the molecular factors involved in osteoblast proliferation and differentiation in order to improve bone formation and treat bone disease. Recent studies demonstrate that many ‘axon guidance’ molecules play important roles in the development and remodeling of bone through their ...

Osteoblastic cells: Differentiation and trans-differentiation
Archives of Biochemistry and Biophysics, 2008The osteoblast is the bone forming cell and is derived from mesenchymal stem cells (MSC) present among the bone marrow stroma. MSC are capable of multi-lineage differentiation into mesoderm-type cells such as osteoblasts and adipocytes. Understanding the mechanisms underlying osteoblast differentiation from MSC is a central topic in bone biology that ...

Steroid Sulfatase Activity in Osteoblast Cells
Biochemical and Biophysical Research Communications, 1997We have demonstrated steroid sulfatase activity in osteoblast cells and characteristics of the enzyme were also investigated. Cell free homogenate of rat osteoblast cell line, UMR106-01 and human osteoblast cell lines, MG-63, HOS were incubated with [3H] dehydroepiandrosterone-sulfate (DHEA-sulfate) or [3H] estrone-sulfate (E1-sulfate).

Circulating Osteoblast-Lineage Cells in Humans
New England Journal of Medicine, 2005Although current evidence suggests that only a minuscule number of osteoblast-lineage cells are present in peripheral blood, we hypothesized that such cells circulate but that their concentration has been vastly underestimated owing to the use of assays that required adherence to plastic.

Collagenase synthesis by osteoblast-like cells
Calcified Tissue International, 1984Cultures of osteoblast-like cells from a rat sarcoma and osteoblast-enriched populations of rat calvarial cells synthesize and secrete a true collagenase and collagenase inhibitor. The enzyme, which is produced in a latent form, appears to be similar to the enzyme produced by fibroblasts.
