The cartilagenous tissue of mandibular condyles of newborn mice contains progenitor cells as well as young and mature chondrogenic cells. During in vitro cultivation of the tissue, progenitor cells undergo osteogenic differentiation and form new bone (Silbermann, M., D. Lewinson, H. Gonen, M. A. Lizarbe, and K. von der Mark. 1983. Anat. Rec. 206:373-383). We have studied the expression of genes...
The osteogenic differentiation of mesenchymal stem cells (MSCs) was assessed by determining the gene expression levels of proteins; osteocalcin (OSC), osteonectin (OSN) and osteopontin (OSP) based on electrochemical detection protocol combined with genomagnetic assay in parallel to real-time PCR analysis. Genomagnetic assay was performed using streptavidin coated commercial magnetic particles (...
Breast cancer is a heterogeneous disease with a poorly defined genetic landscape, which poses a major challenge in diagnosis and treatment. By massively parallel mRNA sequencing, we obtained 1.2 billion reads from 17 individual human tissues belonging to TNBC, Non-TNBC, and HER2-positive breast cancers and defined their comprehensive digital transcriptome for the first time. Surprisingly, we id...
The aim of this study was to clarify the function of amelogenin, the major protein of enamel matrix derivative, on the proliferation, differentiation, and mineralization of cultured rat bone marrow stem cells (BMSCs), toward the establishment of future bone regenerative therapies. No differences in the morphology of BMSCs or in cell numbers were found between amelogenin addition and additive-fr...
The normal duct-lobular system of the breast is lined by two epithelial cell types, inner luminal secretory cells and outer contractile myoepithelial cells. We have generated comprehensive expression profiles of the two normal cell types, using immunomagnetic cell separation and gene expression microarray analysis. The cell-type specificity was confirmed at the protein level by immunohistochemi...
Extraskeletal osteosarcoma is a very rare tumor in humans and animals including rats. This paper describes a case of extraskeletal osteosarcoma observed in the glandular stomach of an aged female Fischer 344 rat. Grossly, a whitish solid mass was observed at the greater curvature of the glandular stomach. Histologically, the tumor consisted of both atypical polygonal and pleomorphic spindle-sha...
Sparc (Osteonectin), a matricellular glycoprotein expressed by many differentiated cells, is a major non-collagenous constituent of vertebrate bones. Recent studies indicate that Sparc expression appears early in development, although its function and regulation during embryogenesis are largely unknown. We cloned zebrafish sparc and investigated its role during development, using a mo rpholino ...
Evolutionary Selection of Bone Mineral Hydroxyapatite Binding Peptides Using Landscape Phage Library
The goal of this work is to identify a peptide that can specifically bind bone mineral hydroxyapatite [(Ca5(PO4)3OH)2] from a phage-displayed random peptide library. Instead of using pIII library where random peptides are displayed at the tip of filamentous phage, we used landscape phage libraries, in which random octa-peptides or nona-peptides are displayed on all the N-termini of the pVIII (m...
