Identification of pre-osteonectin produced by cell-free translation of fetal porcine calvarial mRNA.
BACKGROUND Osteosarcomas (OS) are aggressive neoplasms with a wide range of morphologic patterns. MATERIALS AND METHODS OS cases (primary and xenotransplanted) with paraffin blocks available were collected and included in tissue microarrays (TMAs). A morphologic evaluation including the different passages in mice was carried out according to the new WHO criteria. In addition, TMAs were analyz...
PURPOSE The purpose of this study was to investigate the effects of the immunosuppressants FK506 and cyclosporin A (CsA) on the osteogenic differentiation of rat mesenchymal stem cells (MSCs). METHODS The effect of FK506 and CsA on rat MSCs was assessed in vitro. The MTT assay was used to determine the deleterious effect of immunosuppressants on stem cell proliferation at 1, 3, and 7 days. Al...
Human mesenchymal stem cells (MSCs) are a promising candidate cell type for regenerative medicine and tissue engineering applications. Exposure of MSCs to physical stimuli favors early and rapid activation of the tissue repair process. In this study we investigated the in vitro effects of pulsed electromagnetic field (PEMF) treatment on the proliferation and osteogenic differentiation of bone m...
In vitro metabolic and respiratory acidosis selectively inhibit osteoblastic matrix gene expression.
Clinically, a decrease in blood pH may be due to either a reduction in bicarbonate concentration ([H[Formula: see text]], metabolic acidosis) or an increase in[Formula: see text] (respiratory acidosis). In mammals, metabolic acidosis induces a far greater increase in urine calcium excretion than respiratory acidosis. In cultured bone, metabolic acidosis induces a marked increase in calcium effl...
