Transplantation of cranial neural crest-derived pericytes from human pluripotent stem cells promotes functional recovery in a murine model of ischemic stroke

Project description:Here, human pluripotent stem cells (including hiPSC and hESC) were induced to differentiate to pericytes (PCs) through the intermediate stage of cranial neural crest stem cells (NCSCs). We sequenced mRNA samples at different stages during NCSC-PCs differentiation of human pluripotent stem cells to generate the gene expression profiles of these cells.

The transcriptional landscape of pericytes in acute ischemic stroke

Project description:The current treatment options for ischemic stroke aim to achieve reperfusion but are time critical. Novel therapeutic approaches that can be given beyond the limited time window of 3 - 4.5 hours are still an unmet need to be addressed to improve stroke outcome. The lack of oxygen and glucose in the area of ischemic injury initiates a pathological cascade leading to blood-brain barrier (BBB) breakdown, inflammation and neuronal cell death, a process that may be intercepted to limit stroke progression. Pericytes located at the blood/brain interface are one of the first responders to hypoxia in stroke and therefore a potential target cell for early stroke interventions. Using single-cell RNA sequencing in a mouse model of permanent middle cerebral artery occlusion, we investigated the temporal differences in transcriptomic signatures in pericytes at 1, 12, and 24 hours after stroke compared to the contralateral hemisphere. Our results reveal a stroke-specific subcluster of pericytes that is present at 12 and 24 hours and characterized by the upregulation of genes mainly related to cytokine signalling and immune response. This study identifies temporal transcriptional changes in the acute phase of ischemic stroke that reflect the early response of pericytes to the ischemic insult and its secondary consequences and may constitute potential future therapeutic targets.

Cranial pericytes derived from neural crest cells reveal an inherent cell type-specific defect in Alzheimer's Disease

Project description:Forebrain microvasculature is defective in Alzheimer's disease. To model the role of cranial pericytes in influencing endothelial cell functions, we developed a method for cranial-pericyte derivation from iPSCs. Our studies reveal inherent defects in cranial pericytes from familial AD iPSC. We also demonstrate a similar pathophysiology in perimary pericytes isolated from sporadic AD patients that can be rescued.

Cranial photo-immunologic regulation along the skull-meninges-brain axis for promoting recovery from ischemic brain injury

Project description:Stroke involves in the interaction between central and peripheral immune systems. Skull bone marrows serve as reservoirs for immune cells in brain borders, and can rapidly respond to perturbations in the brain environment. Hence, targeting the skull bone marrow to modulate neuroimmune communications along the calvaria-meninges-brain axis would potentially improve stroke prognosis. Here, we successfully achieved cranial immunomodulation via ultraviolet (UV) irradiation of the interparietal region, which was characterized by rich marrow cavities and channels connecting the skull and meninges. Utilizing the recently-developed long-term clearing cranial window that ensured the integrity of skull, we discovered that the cranial photo-immunologic regulation (CPR) could promote cerebrovascular regeneration and aid in neurovascular repair post ischemic stroke. Single-cell transcriptome analysis revealed that meninge could be a crucial neuroimmune interface for ischemic stroke-induced immune responses. And, CPR could restore the stroke-induced alterations in cellular gene expression, especially meningeal B cells. Further we demonstrated that CPR could effectively alleviate the excessive suppression of meningeal B cell activation caused by ischemic stroke. This work opens avenues for immunoregulation through the skull-meninges-brain axis and provides valuable insights for immunomodulatory therapies in brain diseases.

Post-transcriptional regulation in cranial neural crest cells expands developmental potential [I]

Project description:Developmental potential is progressively restricted after germ layer specification during gastrulation. However, cranial neural crest cells challenge this paradigm, as they develop from anterior ectoderm yet give rise to both mesodermal derivatives of the craniofacial skeleton and ectodermal derivatives of the peripheral nervous system. How cranial neural crest cells differentiate into multiple lineages is poorly understood. Here, we demonstrate that cranial neural crest cells possess a transient state of increased chromatin accessibility; and that the earliest premigratory neural crest are biased towards either a neuronal or ectomesenchymal fate, with each lineage expressing distinct factors from the pluripotent state. We profile the spatiotemporal emergence of each neural crest population and demonstrate that the ectomesenchymal lineage forms prior to the neuronal progenitors. Expression of the pluripotency microRNA family miR-302 is maintained in cranial neural crest cells and genetic deletion leads to precocious specification of the ectomesenchymal lineage. We find that miR-302 directly targets Sox9 to slow the timing of ectomesenchyme induction and regulates multiple genes involved in chromatin condensation to maintain accessibility for neuronal differentiation. Loss of mir-302 results in reduced chromatin accessibility in the neuronal progenitor lineage of neural crest and a reduction in peripheral neuron differentiation. Our findings reveal a post-transcriptional mechanism governed by miRNAs from pluripotency as an important mechanism to expand developmental potential of cranial neural crest.

Single-cell profiling of cranial neural crest diversification across a vertebrate lifetime

Project description:The cranial neural crest (CNC) is a vertebrate-specific population that generates a huge diversity of derivatives, including the bulk of the connective and skeletal tissues of the head. How neural crest cells generate the appropriate cell types for distinct head regions over time remains unresolved. Here we profile RNA expression (scRNAseq) and chromatin accessibility (snATACseq) of the zebrafish cranial neural crest lineage at single-cell resolution from embryos to adults.
