Analysis of embryoid bodies following induction of ectopic Msgn1 expression for up to 48 hours. Msgn1, a bHLH transcription factor, is a target of Wnt3a, a signaling protein that functions in the segmentation clock and the determination front during somitogenesis.

(Submitter supplied) Msgn1 is a bHLH transcription factor and is a direct target gene of the Wnt/b-catenin signaling pathway. During mouse embryogenesis, Msgn1 is expressed in the mesodermal compartment of the primitive streak and is required for the differentiation of presomitic mesoderm. Msgn1-/- mutants show defects in somitogenesis leading to a lack of trunk skeletal muscles, vertebra and ribs. The goal of this study is to dissect the molecular and cellular function of Msgn1 in Embryonic Stem Cells (ESC) and mouse development. more...

(Submitter supplied) During mammalian gastrulation, pluripotent epiblast stem cells migrate through the primitive streak to form the multipotent progenitors of the mesoderm and endoderm germ layers. Msgn1 is a bHLH transcription factor and is a direct target gene of the Wnt/bcatenin signaling pathway. Msgn1 is expressed in the mesodermal compartment of the primitive streak and is necessary for the proper development of the mesoderm. more...

(Submitter supplied) Stem cell-derived tissues have wide potential for modelling developmental and pathological processes as well as cell-based therapy. However, it has proven difficult to generate several key cell types in vitro, including skeletal muscle. In vertebrates, skeletal muscles derive during embryogenesis from the presomitic mesoderm (PSM). Using PSM development as a guide, we establish conditions for the differentiation of monolayer cultures of human pluripotent stem (hPSC) cells into PSM-like cells without the introduction of transgenes or cell sorting. more...

(Submitter supplied) The transcriptional mechanisms driving lineage specification during development are still largely unknown as the interplay of multiple transcription factors makes it difficult to dissect these molecular events. Using a cell-based differentiation platform to probe transcription function, we investigated the role of the key paraxial mesoderm and skeletal myogenic commitment factors, Msgn1, Tbx6, Foxc1, Pax3, Paraxis, Meox1, Six1 and Myf5, in paraxial mesoderm and skeletal myogenesis. more...

(Submitter supplied) The observation that Tcf3 (MGI name: Tcf7l1) bound the same genes as core stem cell transcription factors, Oct4 (MGI name:Pou5f1), Sox2 and Nanog, revealed a potentially important aspect of the poorly understood mechanism whereby Wnts stimulate self renewal of pluripotent mouse embryonic stem (ES) cells. Although the conventional view of Tcf proteins as the β-catenin-binding effectors of Wnt signaling suggested Tcf3 should activate target genes in response to Wnts, here we show that Wnt3a and Tcf3 effectively antagonize each other’s effects on gene expression. more...

(Submitter supplied) Mesoderm differentiation in zebrafish relies on a complex interaction between transcription factors and signaling pathways. Tbx16 is a t-box transcription factor involved in this interaction. Here, we examine downstream targets of tbx16 in the intermediate mesoderm at the 4/5-somite stage and tail mesoderm at the 21-somite stage by comparing wild-type tissues with tissues from the tbx16 mutant, spadetail (spt).

(Submitter supplied) The trunk axial skeleton develops from paraxial mesoderm cells. Our recent study demonstrated that conditional knockout of the stem cell factor Sall4 in mice by TCre caused tail truncation and a disorganized axial skeleton posterior to the lumbar level. Based on this phenotype, we hypothesized that, in addition to the previously reported role of Sall4 in neuromesodermal progenitors, Sall4 is involved in the development of the paraxial mesoderm tissue. more...

(Submitter supplied) In Xenopus, establishment of the anterior-posterior axis involves two key signalling pathways, canonical Wnt and Nodal-related TGF-β. There are also a number of transcription factors that feedback upon these pathways. The homeodomain protein Hex, an early marker of anterior positional information, acts as a transcriptional repressor suppressing induction and propagation of the Spemman organiser while specifying anterior identity. more...

(Submitter supplied) Delta-like 3 (Dll3) is a divergent ligand and modulator of the Notch signaling pathway only identified so far in mammals. Null mutations of Dll3 disrupt cycling expression of Notch targets Hes1, Hes5, and Lfng, but not of Hes7. Compared with Dll1 or Notch1, the effects of Dll3 mutations are less severe for gene expression in the presomitic mesoderm, yet severe segmentation phenotypes and vertebral defects result in both human and mouse. more...

(Submitter supplied) 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. more...

(Submitter supplied) Scl/Tal1 confers hemogenic competence and prevents cardiomyogenesis in embryonic endothelium. Here we show that Scl both directly activates a broad gene regulatory network required for hematopoietic stem/progenitor cell (HS/PC) development, and represses transcriptional regulators required for cardiogenesis. Cardiac repression occurs during a short developmental window through Scl binding to distant cardiac enhancers that harbor H3K4me1 at this stage. more...
