Mathematical model of electrotaxis in osteoblastic cells
Bioelectrochemistry, 2012Electrotaxis is the cell migration in the presence of an electric field (EF). This migration is parallel to the EF vector and overrides chemical migration cues. In this paper we introduce a mathematical model for the electrotaxis in osteoblastic cells.

Autoregulation of bone sialoprotein gene in pre-osteoblastic and non-osteoblastic cells
Biochemical and Biophysical Research Communications, 2004Regulation of the bone sialoprotein (BSP) gene is important in the differentiation of osteoblasts, in bone matrix mineralization, and in tumor metastasis. We investigated BSP gene transcription by performing functional analysis of the 9256bp of the 5' flanking region of the murine BSP gene containing its promoter. We found that the forced expression of

Osteoblast-like cells of the hypophysectomized rat: a model of aberrant osteoblast development
American Journal of Physiology-Endocrinology and Metabolism, 2000In a previous work, we demonstrated that the osteoprogenitors derived from the marrow stroma of the hypophysectomized (HX) rat demonstrate enhanced proliferative and differentiation capacities when placed in an optimal microenvironment. In this study, we sought to investigate the potential of the trabecular osteoblast-like cells of the HX rat.

Osteogenesis requires close co-operation with angiogenesis to create vascularized bone tissue. In this study, an indirect co-culture model using osteoblasts (OBs), primary endothelial cells (ECs) and Matrigel interlayer was established to understand the impact of each cell type on the other.

We investigated stem cell factor (SCF) expression in osteoblasts because mast cells, which occur ectopically in hyperparathyroid bone, are induced by SCF. Nontransformed osteoblasts and Saos2 or MG63 cells expressed SCF in response to PTH. Western analysis showed only large, cell-associated isoforms, Mrs approximately 40-48 kD.

In rat osteoblast-like cells, a time-dependent sequence of growth and differentiation-dependent genes has been identified and a model of osteoblast differentiation in culture suggested. We investigated the expression of the bone matrix-associated proteins osteonectin and procollagen I and of the bone cell phenotype-related proteins alkaline phosphatase

Comparative effect of cadmium on osteoblastic cells and osteoclastic cells
Archives of Toxicology, 1993Cadmium(Cd) has been thought to disturb the bone metabolism directly. The mechanism for the bone lesion is unknown, however. To examine the effects of cadmium on bone metabolism, we compared its effects on osteoblasts and osteoclasts in vitro. We used an established cell line, MC3T3-E1, as osteoblasts and tartrate resistant acid phosphatase (TRACP ...

Effects of Amylin on Human Osteoblast-Like Cells
Peptides, 1997Amylin has been reported to have bone-conserving effects. In the present study we evaluated the possible activity of the peptide on human osteoblast-like (hOB) cells in primary culture. Amylin between 10(-9) and 10(-6) M, dose-dependently stimulated cell proliferation with a maximal effect (200%) at 10(-6) M.
