Human embryonic stem cells (hESC) exposed to the growth factor bone morphogenic protein 4 (BMP4) in the absence of FGF2 have been used as a model to study the development of placental development. However, little is known about the cis-regulatory mechanisms underlying this important process. In this study, we used the public available chromatin accessibility data of hESC H1 cells and BMP4-induced trophoblast (TB)cell lines to identify DNase I hypersensitive sites (DHSs) in the two cell lines, as well as the transcription factor binding sites within the DHSs...

Bone morphogenetic protein 2 (BMP2, HGNC:1069, GeneID: 650) is a classical morphogen; a molecule that acts at a distance and whose concentration influences cell proliferation, differentiation, and apoptosis. Key events requiring precise Bmp2 regulation include heart specification and morphogenesis and neural development. In mesenchymal cells, the concentration of BMP2 influences myogenesis, adipogenesis, chondrogenesis, and osteogenesis. Because the amount, timing, and location of BMP2 synthesis influence pattern formation and organogenesis, the mechanisms that regulate Bmp2 are crucial...

AIM: To evaluate the effect of exogenous recombinant human bone morphogenic protein-7 (rhBMP-7) on transforming growth factor-β (TGF-β)-induced epithelial mesenchymal cell transition (EMT) and assessed its antifibrotic effect via topical application. METHODS: The cytotoxic effect of rhBMP-7 was evaluated and the EMT of human corneal epithelial cells (HECEs) was induced by TGF-β. HECEs were then cultured in the presence of rhBMP-7 and/or hyaluronic acid (HA). EMT markers, fibronectin, E-cadherin, α-smooth muscle actin (α-SMA), and matrix metaloproteinase-9 (MMP-9), were evaluated...

PURPOSE: The synthetic 15 amino acid biomimetic peptide sequence (P15) derived from a region of the alpha (α)-1 chain of collagen I, has been shown to promote α2 integrin activation and enhance intramembranous ossification. In this study, we ask if the P15 peptide also enhances bone formation through endochondral ossification, and determine if direct binding of α2 integrin with P15 mediates integrin activation. METHODS: Mesenchymal cells (C3H10T1/2) were cultured in chondrogenic media and the expression of chondrogenic markers and integrin activation was determined by Western blot and fluorescent immunohistochemistry...

Prostate cancer (PCa) is the second leading cause of death among men in Europe and US. The metastatic dissemination pattern of PCa is unique, developing bone metastasis as the only site of progression, consequently with a prognosis very poor. The cancer cells interactions within the surrounding bone environment are critical for tumor growth and progression. SPARC (Secreted Protein, Acidic and Rich in Cysteine) is described to be involved in PCa cells migration and invasion into bone. 3D in vitro systems that are able to closely resemble the in vivo microenvironment are recently taking importance in cancer research...

Controlling the phenotype of mesenchymal stem cells (MSCs) through the delivery of regulatory genes is a promising strategy in tissue engineering (TE). Essential to effective gene delivery is the choice of gene carrier. Non-viral delivery vectors have been extensively used in TE, however their intrinsic effects on MSC differentiation remain poorly understood. The objective of this study was to investigate the influence of three different classes of non-viral gene delivery vectors: (1) cationic polymers (polyethylenimine, PEI), (2) inorganic nanoparticles (nanohydroxyapatite, nHA) and (3) amphipathic peptides (RALA peptide) on modulating stem cell fate after reporter and therapeutic gene delivery...

The placenta is the first organ to develop during embryogenesis and is required for the survival of the developing embryo. The placenta is comprised of various trophoblastic cells that differentiate from the extra-embryonic trophectoderm cells of the preimplantation blastocyst. As such, our understanding of the early differentiation events of the human placenta is limited because of ethical and legal restrictions on the isolation and manipulation of human embryogenesis. Human pluripotent stem cells (hPSCs) are a robust model system for investigating human development and can also be differentiated in vitro into trophoblastic cells that express markers of the various trophoblast cell types...

BACKGROUND: The healing process of bone fracture requires a well-controlled multistage and sequential order beginning immediately after the injury. However, complications leading to nonunion exist, creating serious problems and costs for patients. Transforming growth factor-beta 1 (TGF-β1) and bone morphogenic protein 2 (BMP-2) are two major growth factors involved in human bone fracture healing by promoting various stages of bone ossification. In this study, we aimed to determine the role of these factors during the fracture healing of human long bones and assess their impacts on nonunion condition...

High incidence of osteoporotic fractures emphasizes the necessity of developing effective measures to promote osteogenesis. In our study, we investigated a possible role of MAPK-ERK signaling in the TGF-β-mediated osteoblastic differentiation. Our results indicated that TGF-β activated the MAPK-ERK pathway and inhibited osteogenesis in mesenchymal pluripotent cell line, C3H10T1/2, and preosteoblastic cell line, MC3T3 cells. And the downregulation of MAPK-ERK signaling using pharmacological inhibitor U0126 and RNA interference rescued osteoblast differentiation suppressed by TGF-β, which was confirmed by Alkaline phosphatase (ALP) staining and alizarrn red staining and the enhanced expression of osteogenesic markers...

Vascular calcification is commonly seen in elderly people, though it can also appear in middle-aged subjects affected by premature vascular aging. The aim of this work is to test the involvement of microvesicles (MVs) produced by senescent endothelial cells (EC) and from plasma of elderly people in vascular calcification. The present work shows that MVs produced by senescent cultured ECs, plus those found in the plasma of elderly subjects, promote calcification in vascular smooth muscle cells. Only MVs from senescent ECs, and from elderly subjects' plasma, induced calcification...

In this study, we evaluated the efficacy of the combination of autologous mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP) for enhancing structural allogenic bone graft healing in rabbits. For these experiments segmental bone defects (1.5-2 cm) were generated on femoral diaphysis of New Zealand white rabbits and reconstructed via structural allogenic bone grafting and additional intramedullary nail fixation. The structural allografts were subsequently wrapped with Gelfoam containing autologous MSCs and PRP, or PRP alone (control)...

BACKGROUND: Glucosamine sulphate (GS) is essential in the biosynthesis of glycolipids, glycoproteins, glycosaminoglycans (GAGs), hyaluronate, and proteoglycans. Connective tissues primarily contain collagen and proteoglycans and play an important role in skin ageing. OBJECTIVE: The objectives were to assess ex vivo the impact of GS on skin ageing parameters and in vivo the effect of GS on the skin physiology of mature healthy volunteers after oral intake. METHODS: The impact of GS on skin ageing was assessed ex vivo via different immunohistochemical assays and histology and via a clinical study using biopsies...

BACKGROUND: Cell-based therapy is a treatment method in tendon injuries. Bone morphogenic protein 12 (BMP-12) possesses tenogenic activity and was proposed as a differentiating factor for stem cells directed to transplantation. However, BMPs belong to pleiotropic TGF-β superfamily and have diverse effect on cells. Therefore, the aim of this study was to determine if BMP-12 induces tenogenic differentiation of human adipose stem cells (hASCs) and how it affects other features of this population...

The development of vertebrate appendages, especially the limb and feather buds are orchestrated by numerous secreted signalling molecules including Sonic Hedgehog, Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnts. These proteins coordinate the growth and patterning of ectodermal and mesenchymal cells. The influence of signalling molecules is affected over large distances by their concentration (morphogen activity) but also at local levels by the presence of proteins that either attenuate or promote their activity...

Heritable pulmonary arterial hypertension (HPAH) is an autosomal dominantly inherited disease caused by mutations in the bone morphogenic protein receptor 2 gene and/or genes of its signalling pathway in about 85% of patients. We clinically and genetically analysed a HPAH family without mutations in previously described PAH genes. Clinical assessment included electrocardiogram, lung function, blood gas analysis, chest X-ray, laboratory testing, echocardiography and right heart catheterisation in case of suspected disease...

Patients with myelofibrosis (MF) often develop anemia and frequently become dependent on red blood cell transfusions. Results from a phase 2 study for the treatment of MF with the Janus kinase1/2 (JAK1/2) inhibitor momelotinib (MMB) demonstrated that MMB treatment ameliorated anemia, unexpected for a JAK1/2 inhibitor, as erythropoietin-mediated JAK2 signaling is essential for erythropoiesis. Using a rat model of anemia of chronic disease (ACD), we now demonstrate that MMB treatment can normalize hemoglobin and red blood cell numbers...

Purpose: Increased expression of TGF-β2 in primary open-angle glaucoma (POAG) aqueous humor (AH) and trabecular meshwork (TM) causes deposition of extracellular matrix (ECM) in the TM and elevated IOP. Bone morphogenetic proteins (BMPs) regulate TGF-β2-induced ECM production. The underlying mechanism for BMP4 inhibition of TGF-β2-induced fibrosis remains undetermined. Bone morphogenic protein 4 induces inhibitor of DNA binding proteins (ID1, ID3), which suppress transcription factor activities to regulate gene expression...
