(Submitter supplied) In order to dissect pathways enchained in skeletal stem/progenitors by Fibrous Dysplasia mutations, we engineered human skeletal stem/progenitors with the mutation and performed transcriptomic analysis. FD mutation profoundly alters the properties of skeletal stem/progenitors by pushing hBMSCs towards formation of disorganized bone with a concomitant lack of fat development. In addition, the mutation created an altered in trans environment that pushed the overall system towards neovascularization, inflammation and osteoclastogenesis. more...

(Submitter supplied) Background: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with 20% fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. Methods: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis. more...

(Submitter supplied) Bone marrow derived stromal cells (BMSCs) are a multipotent population that supports angiogenesis, wound healing, immunomodulation and plays an active role in the hematopoietic niche. On the other hand, they are also involved in the nurturing of bone marrow tumors and metastasis, showing a pro-tumorigenic behavior. BMSCs secrete a wide range of cytokines, growth factors and matrix proteins that are likely responsible for many of these effects. more...

(Submitter supplied) G protein-coupled receptors (GPCRs) mediate a wide spectrum of physiological functions, including the development, remodeling, and repair of the skeleton. Fibrous dysplasia (FD) of the bone is characterized by fibrotic, expansile bone lesions caused by an activating mutation in GNAS. We previously showed that ColI(2.3)+/Rs1+ mice, in which Gs-GPCR signaling was hyper-activated in osteoblastic cell lineages, developed a fibrotic bone phenotype with trabecularization that could be reversed by normalizing Gs-GPCR signaling, suggesting that targeting the Gs-GPCR or components of the downstream signaling pathway could serve as a promising therapeutic strategy for FD, for which there are no effective medical treatments.The Wnt signaling pathway has been implicated in the pathogenesis of FD-like bone, but the specific Wnts and which cells produce them remains largely unknown. more...
