In vitro differentiation protocol of Paraxial mesoderm from mouse embryonic stem cells (mESCs)

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). 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 a medium supplemented with Rspo3, DMSO and the Bmp inhibitor Noggin. In vivo, the PSM cells are first expressing Msgn1 (posterior PSM marker) . After 3 and 4 days of differentiation of mESCs, Msgn1-positive cells were FACS-sorted and their transcriptome analyzed.

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

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

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). 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

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.

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.
