Project description:Here we performed a ChIP-seq experiment for Tlx3 trancription factor on a sample of mouse embryonic dorsal spinal cord. The result is the generation of the genome-wide maps for Tlx3 binding to chromatin in dILB neurones of the developing dorsal horn.

Project description:This experiment aims at characterizing the transcriptome of embryonic mouse dorsal spinal cord. Dorsal spinal cords dissected from litters of E14.5 wild type embryos of unknown sex were processed for RNA extraction using Trizol and RNeasy Mini kit (Qiagen) extraction procedures. Five replicates of wild type embryos were analyzed, each sample with tissue pooled from three embryos.

Project description:Spinal cord injuries (SCI) result in the loss of motor and sensory function. We are working towards restoring sensation by developing directed differentiation protocols to generate dorsal spinal interneurons (dIs; dI1-dI6) from human embryonic stem cells (hESCs). Here, we present an improved method that produces human dIs via a neuromesodermal progenitor state, the physiological intermediate for spinal cord development. We show that retinoic acid (RA), bone morphogenetic protein 4 (BMP4) and growth differentiation factor (GDF) 11 direct dI identity, while GDF11 and extended time in culture promotes posterior spinal identities. Together, these protocols generate the full complement of dorsal subtypes along the entire anterior-posterior axis of the spinal cord. To benchmark in vitro-derived dIs, we constructed a single-cell RNA-Seq atlas of the human embryonic spinal cord and used it to show that hESC-derived dIs closely match their endogenous counterparts. The atlas also reveals that the dI4/dI5 populations dramatically expand in comparison with the other spinal lineages. Moreover, they have mechanosensory circuit signatures linked to autism spectrum disorder, implicating spinal circuits in autistic phenotypes.

Project description:An exquisite example of form serving function is the dorsal horn of the spinal cord, the gateway to the central nervous system for sensory information from the body. Each sensory input to the dorsal horn targets a specific address within its laminated arrangement of diverse neuronal populations. However, it is not known how this organization emerges during development from an apparently homogenous pool of neural progenitors. Here, we found that both the excitatory and inhibitory cell families of the mouse dorsal horn were born in successive waves as temporal cohorts. The excitatory families then settled into a chronotopic map that transformed their birth order into the dorsal laminae. Diversification of families into refined neuron types was mediated by a dorsal-ventral progenitor gradient of Zic transcription factors. This work uncovered fundamental temporal and spatial factors that establish the cell types and structure of the spinal cord dorsal horn.

Project description:To identify differentially expressed genes in the developmental mouse dorsal spinal cord, we characterized the global gene expression profiling of mouse embryonic dorsal spinal cord commissural neurons at E10.5, E11.5 and E12.5. We used the Affymetrix Mouse Exon 1.0 ST Array platform to analyze the gene expression profiling. We included the gene expression data obtained from dorsal spinal cord commissural neuron at different embryonic stage. 2 Biological replicates were performed.
