Project description:We used human embryonic stem cell-derived retinal ganglion cells (RGCs) to characterize the transcriptome of 1,174 cells at the single cell level. The human embryonic stem cell line BRN3B-mCherry A81-H7 was differentiated to RGCs using a guided differentiation approach. Cells were harvested at day 36 and incubated with THY1 antibody (Miltenyi) before undergoing FACS. THY1 positive and THY1 negative cells were subsequently prepared for single cell RNA sequencing. Single cell suspensions were loaded onto 10X Genomics Single Cell 3' Chips along with the reverse transcription master mix as per the manufacturer's protocol for the Chromium Single Cell 3' v2 Library (10X Genomics; PN-120233), to generate single cell gel beads in emulsion. Libraries were then sequenced on an Illumina HiSeq 2500.
Project description:Mouse embryonic fibroblasts were reprogrammed into retinal ganglion cell-like neurons by overexpressing Ascl1/Brn3b/Isl1 transcription factor combination in 13 days.
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.
Project description:The goal of this study was to characterize the transcriptomes of intrinsically-photosenstive retinal ganglion cells that innervate different retinorecipient target regions in the brain
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
Project description:This study was designed to investigate to test the effect of exosomes from urine-derived mesenchymal stem cells (USCs) on the survival and viability of aging retinal ganglion cells (RGCs), and explored the preliminary related mechanisms. The sequencing outcomes demonstrated 117 upregulated genes and 186 downregulated genes in normal RGCs group vs aging RGCs group, 137 upregulated ones and 517 downregulated ones in aging RGCs group vs aging RGCs+USCs medium group. These DEGs involves in numerous positive molecular activities to promote the recovery of RGCs function.
