SummaryThe binding of prostaglandin E2 (PGE2) to bone cells was studied to provide direct evidence for the existence of specific receptors in bone. Bone cells were isolated by collagenase digestion of fetal and newborn rat calvaria. Isolated cells were incubated with3H-PGE2 and collected on Millipore filters. Specific binding was determined by subtracting the binding that occurred with 10−6 M non-radioactive PGE2 and3H-PGE2 from that with3H-PGE2 alone. With heterogeneous cell preparations and… 

Prostaglandin-Induced changes in calcium uptake and cAMP production in osteoblast-like cells: Role of protein kinase C

The results suggest that PKC is involved in the down-regulation of PGE2-induced increases in calcium uptake and cAMP production in the Saos-2 osteoblastic cell line.

Adriamycin inhibits PTH-mediated but not PGE2-mediated stimulation of cyclic AMP formation in isolated bone cells

Results suggest that adriamycin selectively alters the interaction between PTH and its receptor or impairs the transmission of information from hormone-receptor complex to adenylate cyclase (or both), perhaps by binding to specific lipid domains in the plasma membrane.

Graphene oxide enrichment of collagen membranes improves DPSCs differentiation and controls inflammation occurrence.

GO coated membranes are not toxic for DPSCs, induce a faster DPSCs differentiation into odontoblasts/osteoblasts and may represent good alternative to conventional membranes thus ensuring more efficient bone formation and improving the clinical performance.

Osteoblastic differentiating potential of dental pulp stem cells in vitro cultured on a chemically modified microrough titanium surface.

Results suggest that test surface is more osteoinductive, representing a start point for in vivo studies aiming at the construction of more biocompatible dental implants, whose integration and clinical performance are improved and some undesired effects, such as implant stability loss and further surgical procedures, are reduced.

Reduced graphene oxide: osteogenic potential for bone tissue engineering.

Reducing the Col-GO scaffolds can effectively activate the differentiation of hBM-MSCs into osteoblasts after 14 days, even without the addition of an osteogenic differentiation medium, highlighting that GO and its reduced form have considerable potential as bone substitutes for orthopaedic and dental applications.

Osteoid Osteoma and Osteoblastorna

Preoperative localization with computed tomography (0 scans and intraoperative confirmation of location and resection with radioscintigraphy have dramatically reduced the recurrence rate in the last 26 patients) and extreme high levels of prostaglandin metabolites have been found in osteoid osteomas and may explain the inflammatory features of the lesions.

The effect of budesonide on orthodontic induced root resorption

It seems budesonide could increase root resorption, but in the presence of orthodontic force this effect is negligible.

Fabrication and characterization of PHEMA–gelatin scaffold enriched with graphene oxide for bone tissue engineering

ALP analysis indicated that the PHEMA–Gel–GO scaffolds could efficiently cause the differentiation of hBM-MSCs into osteoblasts after 21 days, even without the addition of the osteogenic differentiation medium.

Case report 674

: We report the case of a man with generalized osteosclerosis secondary to well-differentiated lymphocytic lymphoma. This finding is considered to be exceptional in this type of lymphoma, especially



Effects of prostaglandins and other drugs on the cyclic AMP content of cultured bone cells.

Prostaglandins: stimulation of bone resorption in tissue culture.

In vivo studies demonstrated that injections of PGE1 in parathyroidectomized rats did not increase serum calcium concentration, whileParathyroid extract (4–40 U/rat) was effective, and in vitro studies demonstrated the effects of P GE1 were inhibited by thyrocalcitonin and cortisol.

Effect of prostaglandin endoperoxides and metabolites on bone resorption in vitro

The early products of arachidonic acid metabolism via the cyclo-oxygenase pathway, the prostaglandin endoperoxides and some of the 13,14-dihydro metabolites of prostaglandsins were found to cause a rapid transient increase in the release of previously incorporated 45Ca from bone, but did not stimulate prolonged resorption.

Biological activities of prostaglandin analogues and metabolites on bone in organ culture

The most straightforward interpretation of these findings is that PGE2 is secreted by certain tumour cells into plasma in such quantity that the steady-state plasma concentration of P GE2 is sufficiently high to stimulate osseous target cells to resorb bone.

Stimulation of bone resorption by various prostaglandins in organ culture.

Prostaglandin regulation of macrophage collagenase production.

The involvement of PGE in the endotoxin-activation of macrophages with resultant production of collagenase is demonstrated and the role of prostaglandins in this effect is demonstrated.


PGE2 is the bone resorption-stimulating factor produced by HSDM1 tumor cells, and that secretion of PGE2 by the tumor in vivo accounts for the relative hypercalcemia observed in tumor-bearing animals.

Homologous and Heterologous Control of Bone Cell Adenosine 3′,5′-Monophosphate Response to Hormones by Parathormone, Prostaglandin E2, Calcitonin, and 1,25-hydroxycholecalciferol*

Heterologous desensitization to parathormone could be produced in both cell types by 1,25-dihydroxycholecalciferol and prostaglandin E2, but not by calcitonin, and cAMP formation was quantified.
