Differentiation protocol assay on Mouse ES cell lines E14 129P2/OlaHsd

ABSTRACT: 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). Treatment of mouse ES cells with a combination of the secreted Wnt activator R-Spondin3 and the BMP inhibitor Noggin generated cells expressing the early PSM marker Mesogenin1 (Msgn1) with high efficiency. To confirm their identity, we mapped gene expression profiles at successive stages of PSM differentiation in vivo and showed that the differentiated ES cells closely corresponded to the posterior PSM domain that expresses Msgn1 and then with time in culture matured to acquire the profile of the anterior Pax3 domain. When grafted into injured adult muscle in vivo these Pax3-expressing-cells generated large numbers of muscle fibers. Our system therefore efficiently produces myogenic precursors in vitro by recapitulating stepwise early myogenic differentiation in vivo. These findings should advance the development of cellular therapies for muscle degenerative diseases. ES cellline E14 129P2/OlaHsd with DMSO, Rspo, and Noggin at Days 3 and 4

Time course assay in Mouse Pre-Somitic Mesoderm

The experiment was designed to have biological triplicate in each pieces. The PSM is a symmetric structure, left and right area were obtained from one embryo, another set of dissection was obtained from another embryo.

Expression data of mESCs differentiated into Paraxial mesoderm

Project description: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 mouse embryonic stem (ES) cells into PSM-like cells without the introduction of transgenes or cell sorting. We differentiated mouse ESCs in serum-free medium supplemented with Rspo3 ( or as an alternative with Chir 9902) and the Bmp inhibitor LDN193189. In vivo, the PSM cells are first expressing Msgn1 (posterior PSM marker) and then mature to express Pax3 (anterior PSM marker). After 4 days of differentiation of mESCs, Msgn1-positive cells were FACS-sorted and their transcriptome analyzed. After 6 days of differentiation, Pax3-positive cells were sorted and their transcriptome analyzed. Mouse ESCs differentiated for 0, 4 and 6 days in serum-free medium containing a Wnt activator, a BMP inhibitor and DMSO, to study paraxial mesoderm in vitro

Genome wide occupancy of Msgn1 in differentiating embryonic stem cells

Project description: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. In order to identify direct Msgn1 targets, we performed transcriptional profiling and CHIP-seq of Msgn1 expressing differentiating ES cells. Integration of these data sets, we found that Msgn1 is a master regulator of PSM differentiation regulating gene expression programs of PSM identity, EMT, motility and Notch segmentation clock.

Pax3 interactome in mouse ES cell-derived mesodermal precursors

Project description:The skeletal myogenic lineage in developing embryos is specified within the somites and requires members of the Paired box (Pax) family of transcription factors. In particular, Pax3 is the first member of this family expressed in the central region of the dermomyotome and it is necessary for specification, migration and survival of the myogenic progenitors that will form the muscles of the limbs, diaphragm and tongue. To investigate Pax3 molecular functions in the developing mesoderm, we generated doxycycline-inducible mouse embryonic stem (ES) cells expressing untagged and HaFlag-tagged-Pax3. These cell lines were used to unbiasedly identify its interacting partners by tandem affinity purification followed by mass spectrometry.

Chromatin accessibility landscape upon induction of Msgn1, Pax3 and Myf5 in mesodermal cells and identification of conserved Pax3 binding sites and target genes during skeletal myogenesis

Project description: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. From this study, we define a genetic hierarchy, with Pax3 emerging as the gatekeeper between the presomitic mesoderm and the myogenic lineage. By assaying chromatin accessibility, genomic binding and transcription profiling in mesodermal cells from mouse and human Pax3-induced embryonic stem cells and Pax3-null E9.5 mouse embryos, we identified conserved Pax3 functions in the activation of the skeletal myogenic lineage through modulation of Hedgehog, Notch, and BMP signaling pathways. In addition, we demonstrate that Pax3 molecular function involves chromatin remodeling of its bound elements through an increase in chromatin accessibility and cooperation with Six4 and Tead2 factors. Together, our data provide the first integrated analysis of Pax3 function, demonstrating its ability to remodel chromatin in mesodermal cells from developing embryos and proving a mechanistic footing for the transcriptional hierarchy driving myogenesis.

Pluripotent stem cell-derived myogenic progenitors remodel their molecular signature upon in vivo engraftment [Microarray]

Project description:Optimal cell-based therapies for the treatment of muscle degenerative disorders should not only regenerate fibers, but provide a quiescent satellite cell pool ensuring long-term maintenance and regeneration. Conditional expression of Pax3/Pax7 in differentiating pluripotent stem cells (PSC) allows the generation of myogenic progenitors endowed with satellite cell-like abilities. To identify the molecular determinants underlying their regenerative potential, we performed transcriptome analyses of these cells along with primary myogenic cells from several developmental stages. Here we show that in vitro generated PSC-derived myogenic progenitors possess a molecular signature similar to embryonic/fetal myoblasts. However, compared to fetal myoblasts, following transplantation they show superior myofiber engraftment and ability to seed the satellite cell niche, respond to multiple re-injuries and contribute to long-term regeneration. Upon engraftment, the transcriptome of Pax3/Pax7-induced PSC-derived myogenic progenitors changes dramatically, acquiring similarity to that of satellite cells, particularly in genes involved in extracellular matrix remodeling. Single cell profiling reveals that these changes are induced, not selected, by the in vivo environment. These findings demonstrate that Pax3/Pax7-induced PSC-derived myogenic progenitors possess proliferative and migratory abilities characteristic of earlier developmental stages, and an intrinsic ability to respond to environmental cues upon skeletal muscle regeneration.
