Genome wide gene expression profiling and methylation profiling of directly reprogrammed osteoblasts from mouse fibroblasts

ABSTRACT: We identified four transcriptional factors, Runx2, Osx, Dlx5, and ATF4, that rapidly and efficiently reprogram mouse fibroblasts derived from 2.3 kb type I collagen promoter-driven green fluorescent protein (Col2.3GFP) transgenic mice into induced osteoblast cells (iOBs). The global transcriptome profiling validated that iOBs resemble primary osteoblasts. Genome-wide DNA methylation analysis demonstrates that within differentially methylated loci, the methylation status of iOBs more closely resembles primary osteoblasts than mouse fibroblasts. We further demonstrate that Col2.3GFP+ iOBs have transcriptome profiles similar to GFP+ cells derived from Col2.3GFP transgenic mouse bone chips.

Microarray on osteoblasts made from bone marrow stromal cells from Bmp2 flox/flox and Bmp2; Prx1-Cre mice

Project description:Enhanced BMP or canonical Wnt (cWnt) signaling are therapeutic strategies employed to enhance bone formation and fracture repair, but the mechanisms each pathway utilizes to specify cell fate of bone-forming osteoblasts remain poorly understood. Among all BMPs expressed in bone, we find that singular deficiency of Bmp2 blocks the ability of cWnt signaling to specify osteoblasts from limb bud or bone marrow progenitors. When exposed to cWnts, Bmp2-deficient cells fail to progress through the Runx2/Osx1 checkpoint and thus do not upregulate multiple genes controlling mineral metabolism in osteoblasts. Cells lacking Bmp2 after induction of Osx1 differentiate normally in response to cWnts, supporting pre-Osx1+ osteoprogenitors as a critical source and target of BMP2. Our analysis furthermore reveals Grainyhead-like 3 (Grhl3) is to date an unidentified transcription factor in the osteoblast gene regulatory network that is induced during bone development and bone repair, and acts upstream of Osx in a BMP2-dependent manner. The Runx2/Osx1 transition therefore receives critical regulatory inputs from BMP2 that are not compensated for by cWnt signaling, and this is mediated at least in part by induction and activation of Grhl3.

TGF-β signaling plays an essential role in the lineage specification of mesenchymal stem/progenitor cells in fetal bone marrow

Project description:TGF-β regulates fetale bone marrow niche emergence. Abrogating TGF-β signaling in mesenchymal cells during development results in a marked expansion of adipocytes and CAR cells in the bone marrow, while osteoblasts are reduced. RNA expression data from Osx-Cre targeted mesenchymal stromal cells obtained from E16.5 mouse hindlimbs of transgenic mice lacking Tgfbr2 in mesenchymal stromal cells or littermate controls.

Wnt inhibitory factor 1 (WIF1) is a marker of osteoblastic differentiation stage and is not silenced by DNA methylation in osteosarcoma

Project description:Purpose: We have used microarrays to identify gene expression profiles that distinguish mouse OS cells from normal pre-osteoblast cells and mature osteoblast cells. Methods: Transcriptional profiles of three cell lines derived from tumors from Osx-Cre p53fl/fl Rbfl/fl (fibroblastic OS) mouse model, and from pre-osteoblast cells (Kusa4b10 mouse bone marrow stromal cell line) and osteoblast cells (derived by in vitro differentiation of the Kusab410 mouse bone marrow stromal cell line) were generated by microarray analysis, each in triplicate, using Affymetrix mouse Gene1.0ST arrays. Transcriptional profiles were analyzed in cell lines derived from tumors from a genetically engineered mouse model of human osteosarcoma (Osx-Cre p53fl/fl Rbfl/fl) and osteoblast cells derived from the Kusa4b10 mouse bone marrow stromal cell line, in the undifferentiated state (pre-osteoblasts) and differentiated state (osteoblasts).

Expression Data from Osteoblasts with a cell-type specific Piezo1-deficiency or treated with Yoda 1

Project description:Piezo1 is a cellular mechanosensor that can be activated by the compound Yoda 1. Our aim was to evaluate the role of Piezo1 in skeletal metabolism. We investigated the effect of Yoda 1 or Runx2-Cre mediated Piezo1 deficiency on cultured primary murine calvarial osteoblasts. We used microarray analysis to detail the global gene expression of osteoblasts in response to Piezo1-stimulation and deficiency

Comparison of Osx+ cells and Ocn+ cells in the bone marrow.

Project description:We performed gene expression microarray comparing Osx-mCherry cells and Ocn-Topaz cells isolated from the OsxCre-mCherry;OcnCre-Topaz double transgenic mice by flow cytometry. In the OsxCre-mCherry;OcnCre-Topaz mouse model, Osx+ cells were labeled red, Ocn+ cells were green, and Osx+Ocn+ cells were yellow within the same animal. This system allows isolation of osteolineage subsets within the same animal by flow cytometry.

Ablation of the Mammalian Lectin Galectin-8 Induces Bone Defects in Mice

Project description:Mice overexpressing galectin-8 (gal-8 Tg), a secreted mammalian lectin, exhibit enhanced bone turnover and reduced bone mass, similar to cases of post-menopausal osteoporosis. Gal-8 knockout (KO) mice have increased bone mass accrual at young age, but exhibit accelerated bone loss during adulthood. These phenotypes can be attributed to gal-8-mediated increase in RANKL expression that promotes osteoclastogenesis, combined with direct inhibition of osteoblasts differentiation, evident by reduced BMP signaling, SMAD phosphorylation, and reduced expression of osteoblasts differentiation markers OSX, OCN, RUNX2, DMP-1 and ALP. Gal-8 mRNA positively correlates with the mRNA levels of osteoclastogenic markers RANKL, TRAP and CTSK in human femurs. Collectively, these findings identify gal-8 as a new physiological player in the regulation of bone mass.
