Single cell transcriptome profiling of retinal ganglion cells identifies cellular subtypes

Project description:Retinal ganglion cells (RGCs) convey the major output of information collected from the eye to the brain. Thirty subtypes of RGCs have been identified to date. Here, we analyze 6,225 RGCs (average of 5,000 genes per cell) from right and left eyes by single cell RNA-seq and classify them into 40 subtypes using clustering algorithms. We identify additional subtypes and markers, as well as transcription factors predicted to cooperate in specifying RGC subtypes. Zic1, a marker of the right eye-enriched subtype, is validated by immunostaining in situ. Runx1 and Fst, the markers of other subtypes, are validated in purified RGCs by fluorescent in situ hybridization (FISH) and immunostaining. We show the extent of gene expression variability needed for subtype segregation, and we show a hierarchy in diversification from a cell type population to subtypes. Finally, we present a website for comparing the gene expression of RGC subtypes.

Subcellular expression profiling of the growth cones of retinal ganglion cells (RGC)

Project description:Cue-directed axon guidance depends partly on local translation in growth cones. Many mRNA transcripts are known to reside in developing axons yet little is known about their subcellular distribution or, specifically, which transcripts are in growth cones. Laser capture microdissection (LCM) was used to isolate the growth cones of retinal ganglion cell (RGC) axons of two vertebrate species, mouse and Xenopus, coupled with unbiased genome-wide microarray profiling. Localized mRNA from the isolated growth cones of Xenopus laevis and Mus musculus retinal ganglion cells were subjected to microarray analysis

A gene expression database for retinal neuron subtypes

Project description:The goal of this experiment was to define gene expression patterns of two mouse retinal ganglion cell subsets, labeled by expression of fluorescent proteins in Hb9-GFP and Drd4-GFP mice, all retinal ganglion cells labeled by anti-Thy1 antibody staining.

Direct induction of retinal ganglion cell-like neurons

Project description:Retinal ganglion cells (RGCs) are the projection neurons in the retina that connect the visual sensing tissue to the brain. We found that Ascl1/Brn3b/Isl1 transcription factor combination can quickly and efficiently reprogramming mouse embryonic fibroblasts (MEFs) into retinal ganglion cell-like neurons (iRGCs). Using RNA-seq, we analyzed the transcriptomes of MEFs infected with Ascl1/Brn3b/Isl1-overexpressing viruses on day 2 or day 7 of reprogramming, or the final iRGCs on day 13 of reprogramming.

Transcription profiling of mouse developing retinal ganglion and amacrine cells reveals molecular heterogeneity of

Project description:During development of the central nervous system (CNS), cycling uncommitted progenitor cells give rise to a variety of distinct neuronal and glial cell types. As these different cell types are born, they progress from newly specified cells to fully differentiated neurons and glia. In order to define the developmental processes of individual cell types, single cell expression profiling was carried out on developing ganglion and amacrine cells of the murine retina. Individual cells from multiple developmental stages were isolated and profiled on Affymetrix oligonucleotide arrays. These experiments have yielded an expanded view of the processes underway in developing retinal ganglion and amacrine cells, as well as several hundred new marker genes for these cell types. In addition, this study has allowed for the definition of some of the molecular heterogeneity both between developing ganglion and amacrine cells and among subclasses of each cell type. Experiment Overall Design: Single retinal cells were isolated in tubes containing lysis buffer, their mRNAs were reverse transcribed, and the resulting cDNAs were PCR amplified for 35 cycles. Labeled cDNA samples were hybridized to Affymetrix 430 2.0 microarrays and the data was normalized using MAS5.0 software. Cells were identified post hoc as either developing retinal ganglion cells, amacrine cells or rod photoreceptor cells.

RNA-Seq and ChIP-Seq gene profiling of retinal ganglion cells in Math5Cre-driven Knockout of Ezh2 and G9a in murine retinal ganglion cells at P0

Project description:Epigenetic mark deposition during embryonic development contribute to postnatal homeostasis and tissue stability. Previously, we found out that Ezh2 contributes critically to the function and postnatal cell survival in bipolar cells but not in retinal ganglion cells in the retina. (Yan et al. Postnatal onset of retinal degeneration by loss of embryonic Ezh2 repression of Six1. Sci Report. doi:10.1038/srep33887; (Cheng L, Wong LJ, Yan N, Han RC et al. Ezh2 does not mediate retinal ganglion cell homeostasis or their susceptibility to injury. PLoS One 2018;13(2):e0191853.). In this study, we used RNA-seq to define up- and down regulated genes in both Ezh2 and G9a deficient (Math5Cre; Ezh2f/fG9af/+; dKO) retinal ganglion cells (RGC) to evaluate the hypothesis of Ezh2 and G9a interaction that has been discussed in other tissues but in the retina. ChIP-Seq was applied to evaluate H3K27me3 histone marks in retinal ganglion cells in wild type (WT), Ezh2 (Math5Cre; Ezh2-/-, sKO) and combined G9a-Ezh2 (Math5Cre; G9a+/-Ezh2-/-, dKO) knockout mutant mice at P1.
