Single cell RNA-sequencing reveals cellular heterogeneity and trajectories of lineage specification during murine embryonic limb development

ABSTRACT: The coordinated spatial and temporal regulation of gene expression in the murine hindlimb determines the identity of mesenchymal progenitors and the development of diversity of musculoskeletal tissues they form. Hindlimb development has historically been studied with lineage tracing of individual genes selected a priori, or at the bulk tissue level, which does not allow for the determination of single cell transcriptional programs yielding mature cell types and tissues. To identify the cellular trajectories of lineage specification during limb bud development, we used single cell mRNA sequencing (scRNA-seq) to profile the developing murine hindlimb between embryonic days (E)11.5-E18.5. We found cell type heterogeneity at all time points, and the expected cell types that form the mouse hindlimb. In addition, we used RNA fluorescence in situ hybridization (FISH) to examine the spatial locations of cell types and cell trajectories to understand the ancestral continuum of cell maturation. This data provides a resource for the transcriptional program of hindlimb development that will support future studies of musculoskeletal development and generate hypotheses for tissue regeneration.

Single cell RNA-sequencing reveals placenta cellular heterogeneity in adverse pregnancy

Project description:The placenta is a highly heterogeneous organ and is closely related to adverse pregnancy. The previous bulk sequencing of whole tissue could not show the characteristics of individual cells and the interactions between cells. Here, we select the placental tissues of the gestational diabetes group(GDM), preeclampsia group(PE), advanced age group(GL) and normal control group for single-cell sequencing in order to explain the mechanism of related diseases in more depth.nated spatial and temporal regulation of gene expression in the murine hindlimb determines the identity of mesenchymal progenitors and the development of diversity of musculoskeletal tissues they form.

Proteomics analysis of tibialis anterior muscle and descending thoracic aorta from Mustn1 whole-body knockout mice and wild-type littermates

Project description:Skeletal muscle is a highly adaptive tissue that changes with many physiological stimuli and is composed of many cell types. Upon muscle injury, the concerted action of these cells is required to proceed through the process of inflammation, extracellular matrix remodeling, and restoration of function. To uncover novel genes and molecular pathways important for skeletal muscle remodeling and regeneration, we used a mouse hindlimb unloading and reloading protocol, and performed transcriptomics analysis. This study focuses on the microprotein Mustn1 (Musculoskeletal embryonic nuclear protein 1, also known as Mustang), whose gene expression is increased in muscle at the onset of hindlimb reloading, exercise, and injury. We generated a whole-body Mustn1 knockout mouse model and performed proteomics analysis of muscle and aorta.

Early human fetal lung atlas reveals the temporal dynamics of epithelial cell plasticity [Visium]

Project description:While animal models have provided key insights into conserved mechanisms of how the lung forms during development, human-specific developmental mechanisms are not always captured. To fully appreciate how developmental defects and disease states alter the function of the lungs, studies in human lung models are important. Here, we sequenced >150,000 single single-cells from 19 healthy human fetal lung tissues from gestational weeks 10-19 and identified at least 58 unique cell types/states contributing to the developing lung. We captured novel dynamic developmental trajectories from various progenitor cells that give rise to ciliated, pulmonary neuroendocrine cells, and other specialized cell types. We also identified four CFTR-expressing progenitor cell types and pinpointed the temporal emergence and spatial localization of these cell types. These developmental dynamics reveal broader epithelial cell plasticity and novel lineage hierarchies that were not previously reported. Combined with spatial transcriptomics, we identified both cell autonomous and non-cell autonomous signalling pathways that may dictate the temporal and spatial emergence of cell lineages. Finally, we showed that human pluripotent stem cell (hPSC)-derived fetal lung models capture similar cell lineage trajectories specifically through progenitor cells that express abundant levels of the CFTR gene. Overall, this study provides a comprehensive single-cell atlas of the developing human lung, outlining the temporal and spatial complexities of cell lineage development and benchmarks fetal lung cultures from hPSC differentiations to similar developmental window.

Molecular Logic of Cellular Diversification in the Mouse Cerebral Cortex (scRNAseq)

Project description:The mammalian cerebral cortex has an unparalleled diversity of cell types, which are generated during development through a series of temporally orchestrated events that are under tight evolutionary constraint and are critical for proper cortical assembly and function. However, the molecular logic that governs the establishment and organization of cortical cell types remains elusive, largely due to the large number of cell classes undergoing dynamic cell-state transitions over extended developmental timelines. Here, we have generated a comprehensive single-cell RNA-seq and single-cell ATAC-seq atlas of the developing mouse neocortex, sampled every day throughout embryonic corticogenesis and at early postnatal ages, complemented with a spatial transcriptomics time-course. We computationally reconstruct developmental trajectories across the diversity of cortical cell classes, and infer their spatial organization and the gene regulatory programs that accompany their lineage bifurcation decisions and differentiation trajectories. Finally, we demonstrate how this developmental map pinpoints the origin of lineage-specific developmental abnormalities linked to aberrant corticogenesis in mutant animals. The data provides a global picture of the regulatory mechanisms governing cellular diversification in the neocortex.
