Project description:Physiologically, trophoblast progenitor cells differentiate into placental villous cytotrophoblast cells (CTBs). CTBs either differentiate into invasive lineage to yields extravillous cytotrophoblast cells (EVTs), or undergo cell fusion lineage to yields syncytiotrophoblast cells (STBs)，Sonic hedgehog (Shh) together with indian hedgehog (Ihh) and desert hedgehog (Dhh) consist of ligand of hedgehog signaling pathway, which plays pivotal roles in regulating cell proliferation, cell differentiation, organogenesis and development, even involving in tumorigenesis and progression. previous study had summarized and indicatedthat hedgehog proteins played important roles in regulating hematopoiesis, vasculogenesis and angiogenesis during embryogenesis and development. Herein, we investigate the effect of the Sonic Hedgehog morphogen inhibitor Cyclopamine on JAR cells

Project description:Analysis of gene expression levels in response to inhibition of Hh signaling in HT-29 cells using a cDNA microarray technique. Microarray analyses revealed that different genes after treatment with both cyclopamine (an antagonist of SMO) and GANT61 (a specific, small-molecular molecule inhibitor of Glis).

Project description:Endochondral ossification (EO) is the natural route for the regeneration of large and mechanically challenged bone defects. Regeneration occurs via a fibrocartilagenous phase which turns into bone upon vascularization and the formation of a transient collagen type X extra cellular matrix. These two critical initiator of EO are mediated by Hedgehog proteins. We investigated a tissue engineering approach using Sonic Hedgehog (Shh) as a pleiotropic factor regulating the in vitro formation of a vascularized bone tissue precursor for in vivo endochondral bone formation. The tissue engineered graft was formed using human mesenchymal stem cells and prevascularized using human umbilical vein endothelial cells. We show that Shh induced, in vitro, the maturation of the engineered vascular network along with the expression of collagen type X which resulted, in vivo, in an improved vascularization and the rapid formation of large amounts of osteoids through EO. Osteoids further matured into, currently unmatched, clinically relevant amount of lamellar bone including osteoclasts, bone lining cells and bone marrow-like cavities. This result suggests that Hh is a master regulator of EO allowing for the formation of complex tissues with considerable therapeutic potential for bone regeneration. The effect of Cyclopamine on expression of Hedgehog, angiogenesis and axon guidance marker genes was analyzed by seeding a coculture of 92% hMSCs and 8% huvEC supplemented or not in cyclopamine, for 12 days

Project description:The hedgehog (Hh) signaling pathway is important for various developmental processes during embryogenesis and for homeostasis of adult tissue in vertebrates. Aberrant signaling results in severe birth defects and malignancies, respectively. The small molecules SANT-2 and GANT-61 were identified as potential Hh-pathway inhibitors in a reporter gene assay (Shh-light II cells). We aimed to analyze the effects of these compounds on the gene expression level in zebrafish embryos in comparison with the well known Hh-pathway inhibitor cyclopamine. Zebrafish embryos were treated with Ethanol (0,1%) (control), 10 µM Cyclopamine (C), 10 µM SANT-2 (S), and 10 µM GANT-61 (G), for 24 h (0.5 - 24 hpf), respectively; all in 5 independent replicates with 100 zebrafish embryos per treatment. Total RNA was extracted and processed as recommended by Agilent. One color arrays were used and data is given as normalized log2 of the gprocessed signals.

Project description:Study of the tetrapod limb has contributed a great deal to our understanding of developmental pathways and how changes to these pathways affect morphology. Most data on tetrapod limb development is known from amniotes, with far less known about genetic mechanisms of limb development in amphibians. To better understand the mechanisms of limb development in anuran amphibians, we use cyclopamine to inhibit Hedgehog signaling at various stages of limb development in Xenopus. We use transcriptomic analysis following cyclopamine exposure to understand the downstream effects of Hedgehog inhibition on gene expression. We find many aspects of Hedgehog function appear to be conserved with respect to amniotes, including the responses of ptc genes, gremlin, bmp2, and the autoregulatory property of shh. We show that, as was proposed based on experiments in chick, Sonic hedgehog plays two distinct roles in limb development â specification of digit number and specification of digit identity. In contrast to these points of conservation, we find that Hedgehog signaling is required for the maintenance of early limb bud outgrowth in Xenopus, a requirement not known for any other tetrapod. Experiment Overall Design: Eight microarray experiments were performed using RNA extracted from batches of hindlimbs dissected from Xenopus laevis tadpoles. Four of these were experimental groups exposed to cyclopamine at 1 µg/ml for 24 hours before animal fixation, and four were experimental groups exposed to the ethanol, the cyclopamine vehicle, at the same concentration used for cyclopamine vehicle for 24 hours. Each pool of RNA consisted of material from 18-22 hindlimb buds. Two experimental groups and two control groups were from one clutch of tadpoles, and the other four pools were from another clutch. Both samples within each of four paired groups (experimental vs. control) were exposed and processed simultaneously.

Project description:We hypothesized that the occurrence of IVH would reduce interneuron neurogenesis in the medial ganglionic eminence and diminish the population of parvalbumin+ and somatostatin+ cortical interneurons. Since Sonic Hedgehog promotes the production of cortical interneurons, we also postulated that the activation of Sonic Hedgehog signaling might restore neurogenesis, cortical interneuron population, and neurobehavioral function in premature newborns with IVH.
