Bone morphogenetic protein 2 (BMP2), BMP receptor-IA (BMPR-IA), and the BMP2 antagonist Noggin are important proteins involved in regulating the hair follicle (HF) cycle in skin. In order to explore the expression profiles of BMP2, BMPR-IA, and Noggin in the HF cycle of yak skin, we collected adult yak skin in the telogen, proanagen, and midanagen phases of HFs and evaluated gene and protein expression by real-time quantitative polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry...

Several types of serious bone defects would not heal without invasive clinical intervention. One approach to such defects is to enhance the capacity of bone-formation cells. Exogenous bone morphogenetic proteins (BMP) have been utilized to positively regulate matrix mineralization and osteoblastogenesis, however, numerous adverse effects are associated with this approach. Noggin, a potent antagonist of BMPs, is an ideal candidate to target and decrease the need for supraphysiological doses of BMPs. In the current research we report a novel siRNA-mediated gene knock-down strategy to down-regulate Noggin...

A mutation in GDF6 was recently found to underlie a multiple synostoses syndrome. In this report, we describe the second family with GDF6-related multiple synostoses syndrome (SYNS4), caused by a novel c.1287C>A/p.Ser429Arg mutation in GDF6. In addition to synostoses of carpal and/or tarsal bones, at least 6 of 10 affected patients in this family have been diagnosed with mild to moderate hearing loss. In four of them otosclerosis was said to be present, one patient had hearing loss due to severe stapes fixation at the age of 6 years, providing evidence that hearing loss in the GDF6-related multiple synostoses syndrome can be present in childhood...

The present study aimed to assess the effects of therapy with adiponectin (APN) gene-modified adipose-derived stem cells (ADSCs) on pulmonary arterial hypertension (PAH) in rats and the underlying cellular and molecular mechanisms. ADSCs were successfully isolated from the rats and characterized. ADSCs were effectively infected with the green fluorescent protein (GFP)-empty (ADSCs-V) or the APN-GFP (ADSCs-APN) lentivirus and the APN expression was evaluated by ELISA. Sprague-Dawley rats were administered monocrotaline (MCT) to develop PAH...

Developmental neurotoxicity (DNT) testing performed in rats is resource-intensive (costs, time, animals) and bears the issue of species extrapolation. Thus, reliable alternative human-based approaches are needed for predicting neurodevelopmental toxicity. Human induced pluripotent stem cells (hiPSCs) represent a basis for an alternative method possibly being part of an alternative DNT testing strategy. Here, we compared two hiPSC neural induction protocols resulting in 3D neurospheres: one using noggin and one cultivating cells in neural induction medium (NIM protocol)...

Mesenchymal stem cells (MSCs) can differentiate to osteocytes under suitable conditions. In recent years, micro-nucleotides have been progressively used to modulate gene expression in cells due to the consideration of safety. Our present study aimed to investigate whether co-delivery of Noggin-siRNA and antimiR-138 enhances the osteogenic effect of MSCs. Using a murine MSC line, C3H/10T1/2 cells, the delivery efficiency of Noggin-siRNA and antimiR-138 into MSCs was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR)...

Seafood provides a range of health benefits due to its high-protein level. In this study, the osteogenic effect of blue mussel (Mytilus edulis) protein hydrolysates (BMPH) on osteoblast differentiation were examined using mouse mesenchymal stem cells (MSCs). A preparation we called BMPH<1kDa which showed the highest osteogenic effect in MSCs, was prepared by peptic hydrolysis. BMPH<1kDa treatment stimulated osteoblast differentiation with alkaline phosphatase (ALP) induction, osteocalcin and type I collagen activity as well as calcium deposition...

BACKGROUND: Bone metastasis is a key event responsible for morbidity in prostate cancer patients. Interactions between prostate cancer cells and the bone microenvironment facilitate survival of tumour cells and alter bone turnover, a process that is thought to enhance the growth of metastases in this site. This study aimed to test the hypothesis that the presence of tumours cells increases TGFβ signaling in bone and that this regulates the proliferation and differentiation of osteoblastic lineage cells in metastatic sites...

Tissue engineering still needs to assign the molecular basis of pattern formation, tissue induction, and morphogenesis: What next to morphogens and stem cells? Macroporous biomimetic matrices per se, without the addition of the soluble osteogenic molecular signals of the transforming growth factor-β (TGF-β) supergene family, remarkably initiate the induction of bone formation. Carving geometries within different calcium phosphate-based macroporous bioreactors we show that geometric cues imprinted within the macroporous spaces initiate the spontaneous induction of bone...

Arsenic promotes hippocampal neuronal damage inducing cognitive impairments. However, mechanism arbitrating arsenic-mediated cognitive deficits remains less-known. Here, we identified that chronic exposure to environmentally relevant doses of arsenic increased apoptosis, characterized by caspase-3 activation, poly(ADP-ribose) polymerase cleavage and Terminal deoxynucleotidyl transferase dUTP nick-end labeling of rat hippocampal neurons, marked by NeuN. Investigating apoptotic mechanism through invivo and invitro studies revealed that arsenic promoted bone morphogenetic protein-2 (BMP2) expression, supported by increased BMP-receptor2 (BMPR2) and p-Smad1/5 in hippocampal neurons...

Human intestinal organoids (hIOs) derived from human pluripotent stem cells (hPSCs) have immense potential as a source of intestines. Therefore, an efficient system is needed for visualizing the stage of intestinal differentiation and further identifying hIOs derived from hPSCs. Here, 2 fluorescent biosensors were developed based on human-induced pluripotent stem cell (hiPSC) lines that stably expressed fluorescent reporters driven by intestine-specific gene promoters (KLF5(mCherry) and ISX(eGFP)). Then hIOs were efficiently induced from those transgenic hiPSC lines in which monomeric Cherry- or enhanced green fluorescent protein-expressing cells, which appeared during differentiation, could be identified in intact living cells in real time...

A decline in β-cell function is a prerequisite for the development of type 2 diabetes, yet the level of β-cell function in individuals at risk of the condition is rarely measured. This is due, in part, to the fact that current methods for assessing β-cell function are inaccurate, prone to error, labor-intensive, or affected by glucose-lowering therapy. The aim of the current study was to identify novel circulating biomarkers to monitor β-cell function and to identify individuals at high risk of developing β-cell dysfunction...

Even in the adult mammalian brain progenitor cells proliferate and give rise to young neurons which integrate into the neuronal network. The dentate gyrus possesses such a neurogenic niche reactive to external stimuli like physical activity. In most studies mice or rats have been exposed to wheel running for periods of several weeks to activate neurogenesis while early neurogenic processes induced by very short running periods are less well understood. To address this issue, we allowed male C57Bl/6 mice free access to a running wheel for 2 or 7 days...

BACKGROUND: Transplantation of insulin-producing cells is considered an important diabetes therapy. Many research studies have shown that insulin-producing cells can be derived from the in-vitro cultured pancreatic colonies with self-renewal ability and multilineage potential. Even though these progenitor-like colonies have been prepared from adult pancreas cells, the efficient culture method is hardly established and regulation of the colonies is rarely known. We confirmed previously that single cells acquired from adult mouse pancreas could form cyst-like colonies in a 3D semi-solid system containing Matrigel and methylcellulose...

Caudal somites are generated from a pool of progenitor cells located in the tailbud region. These progenitor cells form the presomitic mesoderm that gradually differentiates into somites under the action of the segmentation clock. The signals responsible for tailbud mesoderm progenitor pool maintenance during axial elongation are still elusive. Here, we show that Bmp signaling is sufficient to activate the entire mesoderm progenitor gene signature in primary cultures of caudal mesoderm cells. Bmp signaling acts through the key regulatory genes brachyury (T) and Nkx1-2 and contributes to the activation of several other regulators of the mesoderm progenitor gene network...

Postnatal growth of skeletal muscle largely depends on the expansion and differentiation of resident stem cells, the so-called satellite cells. Here, we demonstrate that postnatal satellite cells express components of the bone morphogenetic protein (BMP) signaling machinery. Overexpression of noggin in postnatal mice (to antagonize BMP ligands), satellite cell-specific knockout of Alk3 (the gene encoding the BMP transmembrane receptor) or overexpression of inhibitory SMAD6 decreased satellite cell proliferation and accretion during myofiber growth, and ultimately retarded muscle growth...

Liver sinusoidal endothelial cells (LSEC) represent a unique, organ-specific type of discontinuous endothelial cells. LSEC instruct the hepatic vascular niche by paracrine-acting angiocrine factors. Recently, we have shown that LSEC-specific transcriptional regulator GATA4 induces expression of BMP2 in cultured endothelial cells (EC) in vitro. Furthermore, angiocrine Bmp2 signaling in the liver in vivo was demonstrated to control iron homeostasis. Here, we investigated GATA4-dependent autocrine BMP2 signaling in endothelial cells by gene expression profiling...

New neurons are generated in the adult hippocampus throughout life and contribute to the functions of learning and memory. Nevertheless, the mechanisms by which disrupted neurogenesis regulates central nervous system (CNS) disorders are not fully understood. Here, we established a novel 3D culture system of hippocampal neurogenesis using air liquid interface (ALI) culture and Matrigel culture from mouse hippocampus tissues. After isolated mouse hippocampus tissue fragments were seeded into ALI wells and cultured in stemness-stimulated media containing Wnt, EGF, Noggin and R-spondin for 7 days, small spheres gradually appeared in the tissues...

OBJECTIVE: We previously reported that low intensity pulsed ultrasound (LIPUS) promotes marrow stromal cell (MSC) osteogenesis and suppresses the LPS-induced inflammatory response in osteoblasts. Here, we examined the effects of LIPUS on human periodontal ligament-derived stem cells (hPDLSCs) in chronic inflammatory bone disease, such as periodontitis. MATERIALS AND METHODS: hPDLSCs were collected from 3 healthy third molars. hPDLSCs were induced to differentiate by either recombinant BMP2 or BMP9 with or without daily LIPUS treatment (20 min/d)...
