Multiome experiment of the neuroepithelial stage of brain organoid developement
Ontology highlight
ABSTRACT: To investigate the heterogeneity during the neuroepithelial stage of organoid development, we performed a multiome experiment on day 15-18 old brain organoids
Project description:In order to provide multi-omic resolution to human retinal organoid developmental dynamics, we performed scRNA-seq and scATAC-seq from the same cell suspension across a time course (6-46 weeks) of human retinal organoid development. This data set covers all the retinal organoid scATAC-seq data generated from IMR90 and 409B2-iCas9 cell lines.

Project description:Bulk ATAC-seq was performed on human, chimpanzee, bonobo, and macaque stem cell-derived cerebral organoids. ATAC-seq was performed on day 60 (2 months old) and day 120 (4 months old) cerebral organoids.
Project description:The human brain has changed dramatically from other primate species, but the genetic and developmental mechanisms behind the differences remains unclear. Here we used single cell RNA sequencing based on 10X technology to explore temporal transcriptomic dynamics and cellular heterogeneity in cerebral organoids derived from human and non-human primates chimpanzee and rhesus macaque stem cells. Using cerebral organoids as a proxy of early brain development, we detect a delayed pace of human brain development relative to the other two primate species. Additional human-specific gene expression patterns resolved to different cell states through progenitors to neurons are also found. Our data provide a transcriptomic cell atlas of primate early brain development, and illustrate features that are unique to humans.
Project description:To study how methanol fixation affects single-cell transcriptomic measurement, two cerebral organoids were dissociated. Cell suspension of each organoid was split into two aliquots. Methanol fixation was applied to one of the two aliquots. Single-cell RNA-seq with 10x Genomics was applied to the two aliquots separately.
Project description:This project used snRNA-seq and Molecular Cartography (single cell spatial transcriptomics) to investigate the relation between morphology and molecular identity in human brain organoids.
Project description:This study demonstrates cellular and molecular mechanisms regulating the generation and function of basal radial glia (bRG), a neural stem cell population that was shown to be enriched in the developing human brain and was involved in the formation of cortical expansion. Here, we studied the role of LGALS3BP, a secreted protein whose RNA expression is enriched in bRGs. Based on a combination of three model systems i) in vitro human cerebral organoids, ii) ex vivo embryonic human fetal tissue and iii) in vivo embryonic mouse cortex, and a wide variety of techniques including single-cell RNA-sequencing, proteomics, and immunostaining, we characterized the role of human LGALS3BP mutations.
Project description:Induced pluripotent stem cell (iPSC) derived organoid systems provide models to study human organ development. Single-cell transcriptome sequencing enables highly-resolved descriptions of cell state heterogeneity within these systems and computational methods can reconstruct developmental trajectories. However, new approaches are needed to directly measure lineage relationships in these systems. Here we establish an inducible dual channel lineage recorder, iTracer, that couples reporter barcodes, inducible CRISPR/Cas9 scarring, and single-cell transcriptomics to analyze state and lineage relationships in iPSC-derived systems. This data set include the iTracer data of 12 cerebral organoids.
Project description:Single cell ATAC-seq (scATAC-seq) was performed at various stages of differentiation of human pluripotent stem cells to 4 month old cerebral organoids. scATAC-seq was performed on the following days of differentiation: day 0 (pluripotent stem cell), day 4 (embryoid body), day 10 (neuroectoderm), day 15 (neuroepithelium), day 30 (1 month old cerebral organoid), day 60 (2 months old cerebral organoid), and day 120 (4 months old cerebral organoid).
