Spatiotemporal single-cell RNA sequencing of developing chicken hearts identifies interplay between cellular differentiation and morphogenesis

Project description:Single-cell RNA sequencing is a powerful tool to study developmental biology but does not preserve spatial information about tissue morphology and cellular interactions. Here, we combine single-cell and spatial transcriptomics with algorithms for data integration to study the development of the chicken heart from the early to late four-chambered heart stage. We create a census of the diverse cellular lineages in developing hearts, their spatial organization, and their interactions during development. Spatial mapping of differentiation transitions in cardiac lineages defines transcriptional differences between epithelial and mesenchymal cells within the epicardial lineage. Using spatially resolved expression analysis, we identify anatomically restricted expression programs, including expression of genes implicated in congenital heart disease. Last, we discover a persistent enrichment of the small, secreted peptide, thymosin beta-4, throughout coronary vascular development. Overall, our study identifies an intricate interplay between cellular differentiation and morphogenesis.

Autophagy is essential for cardiac morphogenesis during vertebrate development

Project description:This study examined the effects of genetic knockdown of autophagy genes on vertebrate cardiac development We performed microarray studies comparing the hearts of control zebrafish embryos to the hearts of embryos with decreased expression of the autophagy genes atg5, becn1 or atg7. The results provide insight into the role of autophagy in developmental morphogenesis. Hearts were purified from 3 day-old zebrafish embryos injected with control or autophagy gene-specific morpholino oligonucleotides. RNA was prepared from all samples and hybridized to zebrafish-specific Affymetricx arrays.

Spatiotemporal expression of regulatory kinases directs the transition from mitosis to cellular morphogenesis in Drosophila

Project description:Embryogenesis depends on a tightly regulated balance between mitosis, differentiation, and morphogenesis. Understanding how the embryo uses a relatively small number of proteins to transition between growth and morphogenesis is a central question of developmental biology, but the mechanisms controlling mitosis and differentiation are considered to be fundamentally distinct. Here we show the mitotic kinase Polo, which regulates all steps of mitosis in Drosophila, also directs cellular morphogenesis after cell cycle exit.

Spatiotemporal Transcriptomics and Metabolomic Analysis Provide Insights into the Nutrition Synthesis in Developing Sorghum Seed

Project description:In this study, we developed a high-resolution spatiotemporal gene expression profiles for sorghum embryo and endosperm, from fertilization through maturation. we identified genes and transcription factors strongly associated with starch and kafirins synthesis. In addition, we pinpointed 499 genes exclusively expressed in seeds, among which 41 were transcription factors, playing pivotal roles in advancing the seed development process.

Spatiotemporal multi-omics decoding of the developing human spinal cord II

Project description:The human spinal cord contains diverse cell types, governed by a series of spatiotemporal events for tissue assembly and functions. However, the regulation of cell fate specification in the human developing spinal cord remains largely unknown. By performing single-cell and spatial multi-omics methods, we integrated the datasets and created a comprehensive human developmental atlas of the first trimester spinal cord. Unexpectedly, we discovered unique events in human spinal cord development, including early loss of active neural stem cells, simultaneous occurrence of neurogenesis and gliogenesis, and distinct spatiotemporal genetic regulations of fate choices. We also identified distinct regulations of cancer stem cells in ependymomas from our atlas. Thus, we demonstrate spatiotemporal genetic regulation of human spinal cord development and its potential to understand novel disease mechanisms.

RNA-seq of CCBE1 KO and WT murine hearts

Project description:CCBE1 is a secreted extracellular matrix protein expressed by epicardial cells but its role during epicardial development was still unknown.Using a Ccbe1 knockout (KO) mouse model, we observed that loss of CCBE1 leads to congenital heart defects including thinner and hyper-trabeculated ventricular myocardium. In addition, Ccbe1 mutant hearts displayed reduced proliferation of cardiomyocyte and epicardial cells. RNA-seq data of CCBE1 KO and WT murine hearts indicated deregulation of genes associated with development and morphogenesis including the epithelial-to-mesenchymal transition.
