Single-cell transcriptome of cerebral organoids with and without methanol fixation

ABSTRACT: 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.

Single cell RNA-seq of great ape 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.

Lineage recording in human cerebral organoids (whole organoids)

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.

Ngn2 induces diverse neuronal lineages from human pluripotency

Project description:Human neurons engineered from induced pluripotent stem cells (iPSCs) through Neurogenin 2 (Ngn2) overexpression are widely used to study neuronal differentiation mechanisms and to model neurological diseases. However, the differentiation paths and heterogeneity of emerged neurons have not been fully explored. Here we used single-cell transcriptomics to dissect the cell states that emerge during Ngn2 overexpression across a time course from pluripotency to neuron functional maturation. We find a substantial molecular heterogeneity in the neuron types generated, with at least two populations that express genes associated with neurons of the peripheral nervous system. Neuron heterogeneity is observed across multiple iPSC clones and lines from different individuals. We find that neuron fate acquisition is sensitive to Ngn2 expression level and the duration of Ngn2 forced expression. Our data reveals that Ngn2 dosage can regulate neuron fate acquisition, and that Ngn2-iN heterogeneity can confound results that are sensitive to neuron type.

The extracellular function of LGALS3BP in neural progenitors during brain development

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.

scRNA-seq of pluripotent stem cell derived human intestinal organoids

Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell derived human intestinal organoids (HIOs) grown in matrigel or a non-adhesive alginate hydrogel after 28 days of in vitro growth. Additionally, we used scRNA-seq to profile HIOs derived in the presence of Neuregulin 1 (NRG1) and/or EGF after 40 days of in vitro growth.

scRNAseq of human iPSC-derived kidney organoids transplanted in the coelomic cavity of chicken embryos compared to untransplanted controls

Project description:Human induced pluripotent stem cell-derived kidney organoids have potential for disease modelling and regenerative medicine purposes. However, they lack a functional vasculature and remain immature in in vitro culture. Here, we transplanted kidney organoids at day 7+12 of differentiation in the coelomic cavity of chicken embryos and then compared them to their respective untransplanted controls at d7+13 and d7+20 using scRNAseq and imaging modalities. We demonstrate vascularization and enhanced maturation of transplanted kidney organoids.
