Mechano-reception in osteoblast-like cells

Biochemistry and Cell Biology, 1995
Response to mechanical stimulation is a basic biological phenomenon. Nearly all cells process mechanical input and respond to it by inducing and modulating biochemical pathways. In organisms with tissues, if the average mechanical load is increased, some tissues can increase their performance and often increase their bulk by cell division. A reduction

OSTEOBLASTIC CELLS ARE INVOLVED IN OSTEOCLAST FORMATION

Endocrinology, 1988
We developed a co-culture system with mouse spleen cells and osteoblastic cells to examine the role of osteoblasts in osteoclast formation. When mouse spleen cells and osteoblastic cells isolated from fetal mouse calvariae were co-cultured in the presence of 10 nM 1 alpha, 25-dihydroxyvitamin D3 [1 alpha,25(OH)2D3], numerous tartrate-resistant acid ...

B cells and osteoblast and osteoclast development

Immunological Reviews, 2005
Summary:  The molecules that regulate bone cell development, particularly at the early stages of development, are only partially known. Data are accumulating that indicate a complex relationship exists between B cells and bone cell differentiation. Although the exact nature of this relationship is still evolving, it takes at least two forms.

The Pericyte as a Possible Osteoblast Progenitor Cell

Clinical Orthopaedics and Related Research, 1992
Bovine capillary and microvessel pericytes were grown in monolayer in standard tissue culture medium supplemented with 10% newborn calf serum at various oxygen tensions for up to ten weeks. The pericytes synthesized alkaline phosphatase and formed colonies that mineralized.

Occurrence of cell junctions and microfilaments in osteoblasts

Cell and Tissue Research, 1975
Osteoblasts in the diaphysis of the tibia during endochondral ossification in young rats are attached to one another by nexus, by "adhaerens" junctions, and by simple appositions. "Adhaerens" junctions and nexus also occur between preosteoblasts and osteoblasts.

Regulation of apoptosis in osteoclasts and osteoblastic cells

Biochemical and Biophysical Research Communications, 2005
In postnatal life, the skeleton undergoes continuous remodeling in which osteoclasts resorb aged or damaged bone, leaving space for osteoblasts to make new bone. The balance of proliferation, differentiation, and apoptosis of bone cells determines the size of osteoclast or osteoblast populations at any given time.

The cell biology of parathyroid hormone in osteoblasts

Current Osteoporosis Reports, 2008
Continuous exposure to parathyroid hormone (PTH) is associated with catabolic effects, whereas intermittent exposure to low doses of PTH is associated with anabolic effects. By controlling osteoblast function, PTH increases bone formation on cancellous, endocortical, and periosteal bone surfaces.

Effects of leukotrienes on osteoblastic cell proliferation

Calcified Tissue International, 1991
Leukotriene B4 (LTB4) is an arachidonic acid lipoxygenase metabolite with well-characterized effects on leukocytes. LTB4 has been implicated in acute inflammatory reactions and in bone resorption. In the present study, the effect of LTB4 on osteoblastic cells was examined. LTB4 inhibited cell proliferation in normal osteoblastic rat calvaria cells in a

Calcium in osteoblast-enriched bone cells

Bone, 1992
The exchangeability, location, and amount of the total calcium in bone cells were studied in relation to their osteoblastic activity. Cells were isolated from neonatal rat calvariae by sequential collagenase digestion and incubated with 45Ca2+ before or after various treatments. 45Ca2+, 40Ca2+, and DNA were determined on each cell sample.

Incorporation of Human Osteoblast Cells and Osteoblast-Like Cells into Porous Hydroxyapatite Scaffolds

Key Engineering Materials, 2005
The object of this study was to investigate methods of seeding cells onto porous hydroxyapatite granules with the aim of optimising cell attachment. Two cells types were used; an osteosarcoma cell line, MG63, and human osteoblasts (HOBs) isolated from trabecular bone.
