Project description:The autonomic nervous system is derived from the neural crest and supplies motor innervation to the smooth muscle of visceral organs, including the lower urinary tract (bladder and urethra, LUT). In rodents, autonomic innervation of the LUT is supplied by the major pelvic ganglia (PG) that lie near the neck of the bladder and proximal urethra. Compared to other autonomic ganglia, the PG are unique in that they harbor both sympathetic and parasympathetic neurons. The coordinated activity of PG neurons is critical for normal functioning of the LUT – however, surprisingly little is known about how PG neuronal diversity is established or what molecular factors control PG development. In this study we conducted transcriptome profiling of Sox10-H2BVenus+ sacral neural crest (NC) progenitors to discover candidate genes involved in PG neurogenesis.

Project description:The enteric nervous system (ENS) is derived from both the vagal and sacral component of the neural crest (NC). Here, we present the derivation of sacral ENS precursors from human PSCs via timed exposure to FGF, WNT and to GDF11 to enable posterior patterning and transition from posterior trunk to sacral NC identity respectively. Using a SOX2::H2B-tdTomato/ T::H2B-GFP dual reporter hPSC line, we demonstrate that both trunk and sacral NC emerge from a double-positive neuro-mesodermal progenitor (NMP). Vagal and sacral NC precursors yield distinct neuronal subtypes and migratory behaviors in vitro and in vivo. Remarkably, xenografting of both vagal and sacral NC lineages is required to rescue a mouse model of total aganglionosis, suggesting novel opportunities in the treatment of severe forms of Hirschsprung’s disease.

Project description:The ENS of vertebrates develops from neural crest cell (NCC) deriving from mainly the vagal neural crest, while NCCs from the sacral level to a less extent. In mouse embryos, the vagal NCCs emigrate from the neural tube adjacent to the somite level from 1-7 at Embryonic day (E)9.0, and sacral NCCs emigrate from the neural tube adjacent to the level of somites caudal to somite 24 in the mouse (in the chick, caudal to somite 28) at E9.5. The spatial difference in cell colonization between vagal and sacral NCCs is that vagal NCCs completely colonize the whole gut, while the distribution of sacral NCCs is only restricted to the hindgut segment. To determine the differences between these two groups of cells, we isolated vagal and sacral NCCs by neural tube explant culture and then performed high-throughput RNA-seq to examine the transcriptional variation. We analyzed that differentially expressed genes (DEGs) by gene ontology (GO) analysis in which the DEGs were enriched in cell adherin, proliferation, transcriptional regulation, et al. This study might help to explore the underlying basis for the different cell behaviors between vagal and sacral NCCs during mouse embryonic development.

Project description:During development, much of the enteric nervous system (ENS) arises from the vagal neural crest that emerges from the caudal hindbrain and colonizes the entire gastrointestinal tract. However, a second contribution to the ENS comes from the sacral neural crest that arises in the caudal neural tube and populates the post-umbilical gut. By coupling single cell transcriptomics with axial-level specific lineage tracing in avian embryos, we compared the contributions of embryonic vagal and sacral neural crest cells to the pre-umbilical and post-umbilical chick ENS and the associated peripheral ganglia (the Nerve of Remak and pelvic plexuses) at embryonic day (E) 10.

Project description:The autonomic nervous system derives from the neural crest (NC) and supplies motor innervation to the smooth muscle of visceral organs, including the lower urinary tract (LUT). During fetal development, sacral NC cells colonize the urogenital sinus to form pelvic ganglia (PG) flanking the bladder neck. The coordinated activity of PG neurons is required for normal urination; however, little is known about the development of PG neuronal diversity. To discover candidate genes involved in PG neurogenesis, the transcriptome profiling of sacral NC and developing PG was performed, and we identified the enrichment of the type 3 serotonin receptor (5-HT3, encoded by Htr3a and Htr3b). We determined that Htr3a is one of the first serotonin receptor genes that is up-regulated in sacral NC progenitors and is maintained in differentiating PG neurons. In vitro cultures showed that the disruption of 5-HT3 signaling alters the differentiation outcomes of sacral NC cells, while the stimulation of 5-HT3 in explanted fetal pelvic ganglia severely diminished neurite arbor outgrowth. Overall, this study provides a valuable resource for the analysis of signaling pathways in PG development, identifies 5-HT3 as a novel regulator of NC lineage diversification and neuronal maturation in the peripheral nervous system, and indicates that the perturbation of 5-HT3 signaling in gestation has the potential to alter bladder function later in life.

Project description:Hirschsprung’s disease (HSCR) is a congenital disease which is characterized by the reduction or absence of neurons and glial cells in the enteric nervous system (ENS). Failure of neural crest cells (NCCs) to colonize the gut during the embryonic development has been considered as one of the possible causes of the disease. In this study, the migration and gene expression of sacral NCCs from the spontaneous mouse mutant Dominant megacolon (Dom) which is a HSCR animal model expressing a mutated transcription factor Sox10, were analyzed in order to identify candidate genes which may possibly affect the NCC migration in the mutant.

Project description:Ectoderm-derived neural crest is a transient structure arising during early embryogenesis in vertebrates. Neural crest consists of four derivatives based on their anterior- to posterior location along the body axis; cranial, vagal, trunk and sacral, respectively. We recently showed that trunk neural crest-specific gene MOXD1 functions as a tumor suppressor in trunk neural crest-derived childhood cancer form neuroblastoma and is essential for proper development of healthy adrenal glands. However, the role of MOXD1 during early embryogenesis is not known. Here, we conditionally knocked out MOXD1 in trunk neural crest cells before they become lineage-committed, using a CRISPR/Cas9 approach in chick embryos. Assessment of embryo growth showed that knockout of MOXD1 delayed development with knockout embryos being smaller. RNA sequencing of trunk-derived neural crest cells from control and knockout embryos showed enrichment of genes connected to gland development, copper ion metabolism and neuroblastoma progression. In conclusion, MOXD1 is important during early and prolonged embryonic development with effects on gland formation, possibly mediated via its role in copper metabolism.
