Project description:Colony Stimulating Factor 1(CSF1) is known to promote osteoclast progenitor survival but its role in regulating osteoclast differentiation and mature osteoclast function are less well understood. Macrophages have the potential to differentiate into osteoclasts and are also considered as osteoclast precursors. The microarray screen was designed to identify potential CSF1 targets in macrophage and osteoclast lineage. Wild type C57/BL6 mice were treated with 0.2 ml 10 % thioglycolate medium (FTG) / mouse by intra-peritoneal injection. Mice were sacrificed one week after injection followed by intra-peritoneal lavage with 15ml PBS. Macrophages were plated at a density of 1.5×10^6/well in 6-well plates and cultured in ?-MEM supplemented with 10% FBS. At 80% confluence, cells were treated with 100ng/ml CSF1 for 12 hours and RNA extracted. Microarray analysis was performed using Affymatrix Mouse Genome 430 2.0 Arrays. Data were analyzed by Gene spring 6.2 software.

Project description:In response to the cytokines, macrophage colony-stimulating factor and receptor activator of NF-kB ligand, monocyte precursors differentiate into bone marrow-derived macrophages (BMDMs) that ultimately fuse to form multi-nucleated osteoclasts, following a tightly controlled genetic program where specific sets of genes are differentially expressed. We used microarrays to examine the gene expression profile underlying mouse osteoclast differentiation.

Project description:Comparison of gene expression of the osteoclast precursor myeloid blast seeded on plastic and on bone, primed with M-CSF for 4 days and culture with M-CSF and RANKL for 1 day. Osteoclasts and macrophages share progenitors that must receive decisive lineage signals driving them into their respective differentiation routes. Macrophage colony stimulation factor M-CSF is a common factor; bone is likely the stimulus for osteoclast differentiation. To elucidate the effect of both, shared mouse bone marrow precursor myeloid blast was pre-cultured with M-CSF on plastic and on bone. M-CSF priming prior to stimulation with M-CSF and osteoclast differentiation factor RANKL resulted in a complete loss of osteoclastogenic potential without bone. This coincided with a steeply decreased expression of osteoclast genes TRACP and DC-STAMP, but an increased expression of the macrophage markers F4/80 and CD11b. Compellingly, M-CSF priming on bone accelerated the osteoclastogenic potential: M-CSF primed cells that had received only one day M-CSF and RANKL and were grown on bone already expressed an array of genes that are associated with osteoclast differentiation and these cells differentiated into osteoclasts within 2 days. This implies that adhesion to bone dictates the fate of osteoclast precursors. Common macrophage-osteoclast precursors may become insensitive to differentiate into osteoclasts and regain osteoclastogenesis when bound to bone or when in the vicinity of bone. Two conditions: Osteoclast precursors on plastic and on bone, n=4, dye swap

Project description:Osteoclasts are multinucleated giant cells generated by the fusion of precursors in response to stimulation with macrophage colony stimulating factor (MCSF) and receptor activator of NF-kB ligand (RANKL). These cells are the only cells capable of resorbing bone. Tartarate-resistant acid phosphatase is an enzyme secreted by osteoclasts that acts in bone resorption. Mice that are deficient for TRAP have shorter bones and their osteoclasts have decreased resorption capacity. In this project, we will isolate bone marrow macrophages from wild type and TRAP deficient mice, and differentiate the cells in osteoclasts in vitro. RNA will be extracted from macrophages and from macrophages stimulated with RANKL for both mouse lines (n=3/group) yielding 4 groups: Group 1 – macrophages from wild type mice, Group 2 – osteoclasts from wild type mice, Group 3 – macrophages from TRAP deficient mice, Group 4 – osteoclasts from TRAP deficient mice. The differential gene expression will be analyzed by RNAseq.

Project description:Osteoclasts are derived from the monocyte/macrophage lineage, but little is known about osteoclast precursors in circulation. Bone marrow cells were subdivided into three populations; RANKhighFmslow, RANKhighFmshigh and RANKlowFmshigh. GeneChip analysis confirmed that the expression levels of monocyte-macrophage markers such as Emr1 (F4/80), Itgam (CD11b) and Csf1 (c-Fms) were lower in the RANKhighFmslow than RANKlowFmshigh population. In contrast, cells in the RANKhighFmslow population expressed higher levels of osteoclast markers such as Car ll (carbonic anhydrase ll), Mmp9 (matrix metalloproteinase 9), Acp5 (acid phosphatase 5) and Tfrc (transferrin receptor). These results suggest that RANKhighFmslow cells express few of the phenotypes of monocytes, and their differentiation into osteoclasts occurs at a slightly more advanced stage than that of the RANKlowFmshigh population. RANKhighFmslow cells and RANKlowFmshigh cells were isolated from bone marrow in ddY mice by FACS (Fluorescent activated cell sorting). Differential expression levels of mRNA were determined by GeneChip analysis.

Project description:Genome wide expression analysis of murine bone marrow osteoclast precursor cells that were cultured for 3 days either with macrophage colony stimulating factor (M-CSF) alone to remain as monocytes or M-CSF + receptor activator of NF-kB (RANKL) to differentiate down the osteoclast lineage. Results provide important information on genes that are regulated by RANKL in order to drive commitment to the osteoclast lineage.

Project description:Bone remodeling is a tightly regulated process that engages degradation and biogenesis of the bone matrix. The process is controlled by two major cell types, bone forming cells-osteoblasts and bone-degrading cells-osteoclasts. We are interested in the bone-resorption mechanism mediated by osteoclasts and wish to identify glycosylation genes that are regulated during the formation of osteoclast cells and determine the function of glycosylation and glycan-binding proteins in the osteoclastogenesis. We propose to examine the gene expression patterns that are altered during the osteoclastogenesis using mouse glyco-chips and RNA samples isolated from osteoclast precursors and mature osteoclasts prepared from mouse bone marrows. 6 chips are requested for the analysis. RNA preparations from mouse bone marrow MG2, MG4, MG6 (mature osteoclasts) and MG1, MG3, MG5 osteoclasts precursors (control) were sent to the Microarray Core (E). The RNA was amplified, labeled, and hybridized to the GLYCOv3 microarrays.

Project description:Inducing the PBMCs from SAPHO patients differentiation into osteoclasts while stimulating with serum exosomes. Compared with exosomes from normal volunteer, we found that about 2/3 of patients’ osteoclast differentiation were inhibited in response to exosomes from SAPHO patients. We present a TMT-labeled quantitative proteomics analysis of the osteoclasts which respond differently to different exosomes.
