Structural and functional changes in the alveolar bone osteoclasts of estrogen-treated rats
(Wiley-Blackwell, 2012-01-01)
This study investigated structural and functional features of apoptotic alveolar bone osteoclasts in estrogen-treated rats. For this purpose, 15 female rats 22 days old were divided into three groups: Estrogen (EG), Sham ...
Jaw and Long Bone Marrows Have a Different Osteoclastogenic Potential
(Springer, 2011-01-01)
Osteoclasts, the multinucleated bone-resorbing cells, arise through fusion of precursors from the myeloid lineage. However, not all osteoclasts are alike; osteoclasts at different bone sites appear to differ in numerous ...
Combined TUNEL and TRAP methods suggest that apoptotic bone cells are inside vacuoles of alveolar bone osteoclasts in young rats
(Blackwell Munksgaard, 2003-04-01)
Although it is generally accepted that osteoclasts breakdown and resorb bone matrix, the possibility that they may also be able to engulf apoptotic osteoblasts/ lining cells and/or osteocytes remains controversial. Apoptosis ...
Apoptotic bone cells may be engulfed by osteoclasts during alveolar bone resorption in young rats
(Churchill Livingstone, 2001-08-01)
The alveolar bone is a suitable in vivo physiological model for the study of apoptosis and interactions of bone cells because it undergoes continuous, rapid and intense resorption/remodelling, during a long period of time, ...
Treatment with tacrolimus enhances alveolar bone formation and decreases osteoclast number in the maxillae: A histomorphometric and ultrastructural study in rats
(F Hernandez, 2008-10-01)
Recent studies have suggested that tacrolimus monotherapy is a beneficial therapeutic alternative for the normalization of cyclosporin- induced bone loss in animal models and humans. The mechanism accounting for this action ...

Jaw and long bone marrow derived osteoclasts differ in shape and their response to bone and dentin
(Elsevier B.V., 2011-06-03)
Increasing evidence suggests the existence of osteoclast diversity. Here we investigated whether precursors obtained from marrow of the mandibula or long bone could give rise to phenotypically different osteoclasts. Formation ...
Immunohistochemical detection of estrogen receptor beta in alveolar bone cells of estradiol-treated female rats: possible direct action of estrogen on osteoclast life span
(Wiley-Blackwell Publishing, Inc, 2009-12-01)
The role of estrogen in bone resorption has been specifically related to the effect of estrogen on the signalling pathway that inhibits the formation of osteoclasts. However, osteoclast apoptosis and a significant reduction ...
