RNA-seq to investigate the adult mouse Muller glia transcriptome

Project description:These data serve as a reference transcriptomic profile for adult mouse retinal Muller glia. Retinas were dissociated into single cell suspensions and sorted into two fractions: a Muller glia-enriched fraction on the basis of Muller glia-specific tdTomato expression and a second fraction containing the remaining retinal cells that were tdTomato-negative. Both fractions were sequenced.

Transcriptome analysis of the uninjured Muller glia (MG) and MG derived retinal progenitors at 4 day post injured zebrafish retina

Project description:The study was aimed at comparing the transcriptome of MG cells of the retina with the progenitors derived from them after an injury. This information will help in the identification of factors that are responsible for the retinal regeneration. Muller glia were isolated by fluorescent activated cell sorting (FACS) using uninjured retinas from transgenice zebrafish (gfap:gfp) where green florescent protein (GFP) is under the control of the glial fibrillary acidic protein (gfap) promoter. MG-derived retinal progenitors were isolated by FACS at 4 days post retinal injury from 1016 tuba1a:gfp transgenic fish where GFP is driven by the tuba1a promoter which is specifically activated in these progenitors. Total RNA was isolated from these cell populations and subjected to microarray analysis to compare their transcriptomes. Samples were prepared in duplicate.

ASCL1 induces neurogenesis in human Muller glia

Project description:In mammals, loss of retinal cells due to disease or trauma is an irreversible process which can lead to blindness. Interestingly, regeneration of retinal neurons is a well-established process in some non-mammalian vertebrates and is driven by the Muller glia (MG), which are able to re-enter the cell cycle and reprogram into neurogenic progenitors upon retinal injury or disease. Progress has been made to restore this mechanism in mammals to promote retinal regeneration: MG can be stimulated to generate new neurons in vivo in the adult mouse retina after the over-expression of the pro-neural transcription factor Ascl1. In this study, we applied the same strategy to reprogram human MG derived from fetal retina and retinal organoids into neurons. Combining scRNA-seq, scATAC-seq, Immunofluorescence, and electrophysiology we demonstrate that human MG can be reprogrammed into neurogenic cells in vitro.

Comparative transcriptomic and epigenomic analysis identifies key regulators of injury response and neurogenic competence in retinal glia

Project description:Injury induces retinal Muller glia of non-mammalian, but not mammalian, vertebrates to generate neurons. To identify gene regulatory networks that control neurogenic competence in retinal glia, we used bulk and single-cell RNA-seq and ATAC-seq analysis to comprehensively profile gene expression and chromatin conformation in Muller glia from zebrafish, chick and mice. This was conducted during glial development, following inner and outer retinal injury, as well as following treatment with extrinsic factors that induce glial reprogramming. Integration of these data, together with functional analysis of candidate genes, identified evolutionarily conserved and species-specific gene regulatory networks controlling glial quiescence, gliosis, and neurogenic competence. In zebrafish and chick, transition from quiescence to gliosis is a necessary stage in acquisition of neurogenic competence, while in mice a dedicated network suppresses this transition and rapidly restores quiescence. These findings may help guide the design of cell-based therapies aimed at restoring retinal neurons lost to disease.
