Project description:Transcriptional Programming of Human Mechanosensory Neuron Subtypes from Pluripotent Stem Cells

Project description:In vitro generation of human peripheral sensory neurons may provide a framework for novel drug screening platforms and disease models of touch and pain. However, derivation of a functionally pure sensory neuron population remains a major unmet challenge. We discovered that, by expressing the transcription factors NGN2 and BRN3A, human pluripotent stem cells can be induced to differentiate into a surprisingly homogenous culture of cold- and mechano-sensing neurons. Although such a neuronal subtype has not been reported in mice, we found molecular evidence of its existence in adult human sensory ganglia. Combining NGN2 and BRN3A programming with neural crest patterning, we produced two additional populations of sensory neurons, including a more specialized mechanosensory neuron subtype. Finally, we applied this system to model a rare inherited sensory disorder, characterized by profound impairment of touch sensation and proprioception, caused by inactivating mutations in PIEZO2. Together these findings establish an approach to specify distinct sensory neuron subtypes in vitro, underscoring the utility of stem cell technology to capture human-specific features of physiology and disease.

Project description:Efficient and homogeneous in vitro generation of peripheral sensory neurons may provide a framework for novel drug screening platforms and disease models of touch and pain. We discover that, by overexpressing NGN2 and BRN3A, human pluripotent stem cells can be transcriptionally programmed to differentiate into a surprisingly uniform culture of cold- and mechano-sensing neurons. Although such a neuronal subtype is not found in mice, we identify molecular evidence for its existence in human sensory ganglia. Combining NGN2 and BRN3A programming with neural crest patterning, we produce two additional populations of sensory neurons, including a specialized touch receptor neuron subtype. Finally, we apply this system to model a rare inherited sensory disorder of touch and proprioception caused by inactivating mutations in PIEZO2.

Project description:The goal of this experiment was to define gene expression patterns of thirteen mouse retinal neuron subsets, labeled by expression of fluorescent proteins in transgenic mice. Neurons expressing xFPs were purified by flow cytometry. Thirteen different neuron subtypes were compared. Two biological replicates, originating from different litters, were collected for each cell type. RNA was extracted from sorted cells and prepared for hybridization to Affymetrix microarrays.

Project description:Direct programming via the overexpression of transcription factors (TFs) aims to control cell fate at a precision that will be instrumental for clinical applications. However, direct programming of terminal fates remains an obscure process. Taking advantage of the rapid and uniquely efficient programming of spinal motor neurons by overexpression of Ngn2, Isl1 and Lhx3, we have characterized gene expression, chromatin and transcription factor binding time-course dynamics during complete motor neuron programming. Our studies point to a surprisingly dynamic programming process. Promoter chromatin and expression analysis reveals at least three distinct phases of gene activation, while programming factor binding shifts from one set of targets to another, controlling regulatory region activity and gene expression. Furthermore, our evidence suggest that the enhancers and genes activated in the final stage of motor neuron processing are dependent on the combined activities of Isl1 and Lhx3 factors with Ebf and Onecut TFs that are themselves activated midway through the programming process. Our results suggest an unexpected multi-stage model of motor neuron programming in which the programming TFs require activation of a set of intermediate regulators before they complete the programming process.

Project description:A variety of mechanosensory neurons are involved in touch, proprioception and pain. Many molecular components of the mechanotransduction machinery subserving these sensory modalities remain to be discovered. Here, we combined recordings of mechanosensitive (MS) currents in mechanosensory neurons with single cell RNA sequencing. In silico analysis of collected data combined with a previous large-scale dataset allowed to link the four identified kinetically distinct MS current subtypes to transcriptomically defined populations of DRG neurons. Moreover, gene expression differential comparison provided a list of candidate genes for mechanotransduction complexes. This dataset constitutes an open-resource to explore further the cell-type-specific determinants of mechanosensory properties.
