Liver fibrosis is overly exuberant wound healing that leads to portal hypertension or liver cirrhosis. Recent studies have demonstrated the functions of bone morphogenetic protein 9 (BMP9) in liver fibrosis, and thus, targeting liver-specific BMP9 abnormalities will become an attractive approach for developing therapeutics to treat liver fibrosis. Here, we reveal that BMP9 serves as a valuable serum diagnostic indicator and efficient therapeutic target to attenuate liver fibrogenesis. Our analysis of biopsies from liver fibrotic patients revealed that higher BMP9 levels accompanied advanced stages of liver fibrosis...

AIMS: Curcumin (diferuloylmethane or [1E,6E]-1,7-bis[4-hydroxy-3-methoxyphenyl]-1,6heptadiene-3,5-dione) is a phenolic natural product derived from the rhizomes of the turmeric plant, Curcuma longa. It is reported to have various biological actions such as anti-oxidative, anti-inflammatory, and anti-cancer effects. However, the molecular mechanism of osteoblast differentiation by curcumin has not yet been reported. MAIN METHODS: The cytotoxicity of curcumin was identified using the 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay...

Differentiated human embryonic stem cells (hESC) continue to provide a model for studying early trophoblast cells (TB), but many questions have been raised regarding their true identity. Therefore, we carried out a global and unbiased analysis on previously published transcriptomic profiles for hESC differentiated to TB by means of bone morphogenetic protein-4 and inhibitors of activin A and fibroblast growth factor-2 signaling (BAP treatment). Our results confirm that BAP treated hESC (ESCd) lack a mesoderm signature and are a subtype of placental cells unlike those present at term...

In vitro embryo development remains suboptimal compared to in vivo development due to the challenge from various stressors associated with in vitro culturing of oocytes. When 0.2 μM lycopene was added to oocyte in vitro maturation and embryo culture media, to assess its antioxidant effects on embryo development, we observed a significant (p<0.05) increase in cleavage and blastocyst development rates compared to the corresponding controls (84.3 ± 0.6% vs. 73.1 ± 1.9% and 41.0 ± 1.4% vs. 33.4 ± 0.7%, respectively)...

Photobiomodulation (PBM) therapy displays relevant properties for tissue healing and regeneration, which may be of interest for the tissue engineering field. Here, we show that PBM is able to improve cell survival and to interact with recombinant human Bone Morphogenetic Protein 4 (rhBMP4) to direct and accelerate odonto/osteogenic differentiation of dental derived mesenchymal stem cells (MSCs). MSCs were encapsulated in an injectable and thermo-responsive cell carrier (Pluronic® F-127) loaded with rhBMP4 and then photoactivated...

Dental pulp cells (DPCs) are valuable cell source for dental regeneration, albeit their application is restricted by limited pluripotency due to current culture condition. Mouse embryonic fibroblasts (MEFs) are served as feeder layer to maintain undifferentiated state of iPSCs and ESCs with long-term in vitro culture. Bone morphogenetic protein 4 (BMP4) plays an important role in the regulation of undifferentiated state and lineage commitment of cells through modulation of microenvironment. However, so far little was known how micro environment affect the multipotency of dental derived cells...

BACKGROUND: Gliomas result in the highest morbidity and mortality rates of intracranial primary central nervous system tumors because of their aggressive growth characteristics and high postoperative recurrence. They are characterized by genetic instability, intratumoral histopathological variability and unpredictable clinical behavior in patients. Proliferation is a key aspect of the clinical progression of malignant gliomas, complicating complete surgical resection and enabling tumor regrowth and further proliferation of the surviving tumor cells...

Multiple growth factors can be administered to mimic the natural process of bone healing in bone tissue engineering. We investigated the effects of sequential release of bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) from polylactide-poly (ethylene glycol)-polylactide (PELA) microcapsule-based scaffolds on bone regeneration. To improve the double emulsion/solvent evaporation technique, VEGF was encapsulated in PELA microcapsules, to which BMP-2 was attached. The scaffold (BMP-2/PELA/VEGF) was then fused to these microcapsules using the dichloromethane vapor method...

The defence collagens C1q and mannose-binding lectin (MBL) are immune recognition proteins that associate with the serine proteinases C1r/C1s and MBL-associated serine proteases (MASPs) to trigger activation of complement, a major innate immune system. Bone morphogenetic protein-1 (BMP-1)/tolloid-like proteinases (BTPs) are metalloproteinases with major roles in extracellular matrix assembly and growth factor signalling. Despite their different functions, C1r/C1s/MASPs and BTPs share structural similarities, including a specific CUB-EGF-CUB domain arrangement found only in these enzymes that mediates interactions with collagen-like proteins, suggesting a possible functional relationship...

Iron-overload cardiomyopathy is prevalent on a worldwide basis and is a major co-morbidity in patients with genetic hemochromatosis and secondary iron overload. Therapies are limited in part due to lack of a valid pre-clinical model, which recapitulates advanced iron-overload cardiomyopathy. Male hemojuvelin knockout (HJVKO) mice, which lack hemojuvelin (HJV), a bone morphogenetic co-receptor protein required for hepcidin expression and systemic iron homeostasis, were fed a high iron diet starting at 4 weeks of age for a duration of 1 year...

PURPOSE: Normal stem cells tightly control self-renewal and differentiation during development, but their neoplastic counterparts, cancer stem cells (CSCs), sustain tumorigenicity both through aberrant activation of stemness and evasion of differentiation. Although regulation of CSC stemness has been extensively studied, the molecular mechanisms suppressing differentiation remain unclear. EXPERIMENTAL DESIGN: We performed in silico screening and in vitro validation studies through western blotting, q-RT-PCR for treatment of WNT and SHH signaling inhibitors and BMP signaling inducer with control and ID1-overexpressing cells...

Traumatic wounds with segmental bone defects represent substantial reconstructive challenges. Autologous bone grafting is considered the gold standard for surgical treatment in many cases, but donor site morbidity and associated post-operative complications remain a concern. Advances in regenerative techniques utilizing mesenchymal stem cell populations from bone and adipose tissue have opened the door to improving bone repair in the limbs, spine, and craniofacial skeleton. The widespread availability, ease of extraction, and lack of immunogenicity have made adipose-derived stem cells (ASCs) particularly attractive as a stem cell source for regenerative strategies...

AKI after cardiac surgery is associated with mortality, prolonged hospital length of stay, use of dialysis, and subsequent CKD. We evaluated the effects of THR-184, a bone morphogenetic protein-7 agonist, in patients at high risk for AKI after cardiac surgery. We conducted a randomized, double-blind, placebo-controlled, multidose comparison of the safety and efficacy of perioperative THR-184 using a two-stage seamless adaptive design in 452 patients between 18 and 85 years of age who were scheduled for nonemergent cardiac surgery requiring cardiopulmonary bypass and had recognized risk factors for AKI...

A bone-remodeling imbalance induced by increased bone resorption and osteoclast formation causes skeletal diseases such as osteoporosis. Induction of osteogenic differentiation of bone marrow stromal cells (BMSCs) leads to bone regeneration. Many researchers have tried to develop new adjuvants as specific stimulators of bone regeneration for therapeutic use in patients with bone resorption. We tried to develop a new adjuvant that has stronger osteogenic differentiation-promoting activity than bone morphogenetic proteins (BMPs)...

Bone morphogenetic protein 2 (BMP2) in chromosomal region 20p12 belongs to a gene superfamily encoding TGF-β-signaling proteins involved in bone and cartilage biology. Monoallelic deletions of 20p12 are variably associated with cleft palate, short stature, and developmental delay. Here, we report a cranioskeletal phenotype due to monoallelic truncating and frameshift BMP2 variants and deletions in 12 individuals from eight unrelated families that share features of short stature, a recognizable craniofacial gestalt, skeletal anomalies, and congenital heart disease...

BACKGROUND: Recent reports have demonstrated that RAF-1L613V (a mutant of RAF-1) mutant mice show bone deformities similar to Noonan syndrome. It has been suggested that RAF-1L613V might abnormally activate osteoblast differentiation of MC3T3-E1 cells. METHODS: To demonstrate that RAF-1 is associated with bone deformity and that RAF-1L613V dependent bone deformity could be inhibited by microRNA-195 (miR-195), we first investigated the amplifying influence of wild-type RAF-1 (WT) or RAF-1L613V (L613V) on the viability and differentiation of MC3T3-E1 cells induced by bone morphogenetic protein-2 (BMP-2) via 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining, quantitative real-time polymerase chain reaction (qRT-PCR) and western blot analysis...
