Project description:We established two iPSC-derived 3D models recapitulating human somitogenesis, Somitoids and Segmentoids. Somitoids recapitulate the temporal sequence of somitogenesis, with all cells undergoing differentiation and morphogenesis in a synchronous manner. On the other hand, Segmentoids recapitulate the spatio-temporal features of somitogenesis, including gene expression dynamics, tissue elongation, sequential somite morphogenesis, and polarity patterning. They therefore provide an excellent proxy to study human somitogenesis.
Project description:This SuperSeries is composed of the following subset Series:; GSE7012: Identif. of oscillatory genes in somitogenesis from functional genomic analysis of C2C12 myoblast line; GSE7015: Identif. of oscillatory genes in somitogenesis from functional genomic analysis of a human mesenchymal stem cell model Experiment Overall Design: Refer to individual Series
Project description:Metabolism is vital to cellular function and tissue homeostasis during human lung development. In utero, embryonic pluripotent stem cells undergo endodermal differentiation towards a lung progenitor cell fate that can be mimicked in vitro using induced human pluripotent stem cells (hiPSCs) to study genetic mutations. To identify differences between wild type and surfactant protein B (SFTPB)-deficient cell lines during endoderm specification towards lung, we used an untargeted metabolomics approach to evaluate the developmental changes in metabolites. We found that the metabolites most enriched during the differentiation from pluripotent stem cell to lung progenitor cell, regardless of cell line, were sphingomyelins and phosphatidylcholines, two important lipid classes in fetal lung development. The SFTPB mutation had no metabolic impact on early endodermal lung development. The identified metabolite signatures during lung progenitor cell differentiation may be utilized as biomarkers for normal embryonic lung development.
