Vascularized human cortical organoids (vOrganoid) model cortical development in vivo

Project description:Modeling the processes of neuronal progenitor proliferation and differentiation to produce mature cortical neuron subtypes is essential for the study of human brain development and the search for potential cell therapies. We demonstrated a novel paradigm for the generation of vascularized organoids (vOrganoids) consisting of typical human cortical cell types and a vascular structure for over 200 days as a vascularized and functional brain organoid model. The observation of sEPSCs (spontaneous excitatory postsynaptic currents), sIPSCs (spontaneous inhibitory postsynaptic currents) and bidirectional electrical transmission indicated the presence of chemical and electrical synapses in vOrganoids. More importantly, single-cell RNA-sequencing analysis illustrated that vOrganoids exhibited robust neurogenesis and that cells of vOrganoids differentially expressed genes related to blood vessel morphogenesis. The transplantation of vOrganoids into the mouse S1 cortex resulted in the construction of functional human-mouse blood vessels in the grafts that promoted cell survival in the grafts. This vOrganoid culture method could not only serve as a model to study human cortical development and explore brain disease pathology but also provide potential prospects for new cell therapies for nervous system disorders and injury.

Medial Ganglionic Eminence and Cortical Organoids Model Human Brain Development and Interneuron Migration [RNA-seq2]

Project description:Organoid techniques provide unique platforms to model brain development and neurological disorders. While organoids recapitulating corticogenesis were established, a system modeling human medial ganglionic eminence (MGE) development, a critical ventral brain domain producing cortical interneurons and related lineages, remains to be developed. Here, we describe a system to generate MGE or cortex-specific organoids from human pluripotent stem cells. These organoids recapitulate the developments of MGE and cortex domains respectively. Population and single-cell transcriptomic profiling revealed transcriptional dynamics and lineage productions during MGE and cortical organoids development. Chromatin accessibility landscapes were found to be involved in this process. Furthermore, MGE and cortical organoids generated physiologically functional neurons and neuronal networks. Finally, we applied fusion organoids as a model to investigate human interneuron migration. Together, our study provides a new platform for generating domain-specific brain organoids, for modeling human interneuron migration, and offers deeper insight into molecular dynamics during human brain development.

Single-cell RNA sequencing of vascularized brain organoids

Project description:Organoids have been widely used as unique models of human brain development and disorders. However, the lack of vasculatures in brain orgnoids limits their application in the study of brain vasculature development and diseases. Here, we described to the generation of vascularized brain organoids (VBOrs) with different brain regions from human embryonic stem cells. The goals of this study are to analyze the cell populations of the new model of vasularized brain organoids cultured from human embryonic stem cells (H9). We found that VBOrs contain variant brain cells inculding neural progenitors, neuronal cells, astrocytes, sparse endothelial cells, and pericytes. The new model of VBOrs should be valuable for addressing questions between brain vasculatures and neural cells.

Bulk RNA-seq of cerebral organoids investigating the role of CHD8 in cortical development

Project description:We used cerebral organoids generated from wildtype and CHD8 +/- human ES cells to study the effects of CHD8, one of the top ASD risk genes, on early cortical development. CHD8 +/- hESC were generated using the CRISPR/Cas9 system to create a deletion within the helicase domain. Cerebral organoids were generated according to the protocol from Lancaster et al 2013 with minor modifications.
