Project description:We elucidate the role of prospero-related homeobox 1 (Prox1) in rendering the mammalian retina incompetent for MG(Muller glia cell)-derived regeneration. Prox1 accumulates in MG in the degenerating human and mouse retinas but not in those in the regenerating zebrafish retina. We investigated whether the transition of MG to proliferative MGPCs occurred in MNU-injured Prox1fg/fg;Chx10-CreERT2 mouse retinas through single-cell RNA sequencing analysis.

Project description:We found that the zebrafish non-coding element careg, which is induced in regenerating fins and heart, also participates in retina regeneration. Its activation persisted mostly in Müller glia from the onset to the termination of retina restoration. To assess the involvement of the careg:EGFP reporter during retina regeneration, we used a chemical injury model with MNU treatment. To identify the molecular profile of these cells, we performed a single-cell RNA sequencing (scRNA-seq) experiment of retinas dissected from adult careg:EGFP zebrafish at 3, 7, and 10 dpMNU. Our control retinas were dissected from fish at 3 days after treatment with heat-inactivated MNU
Project description:Retinal damage causes proliferation of Muller glia, but the degree of proliferation depends on mouse strains. Muller glial proliferation was significantly promoted by the addition of GSK3 inhibitor in 129, but not in B6. We used retinal explant culture as a model for retinal damage which caused preferential photoreceptor death in a few days. We used microarrays to detail the global programme of gene expression regulating the proliferative potential of Muller glia after retinal damage. Total RNA from intact whole retina, retinal tissue cultured for three days, and retinal tissue cultured with chir99021 for three days was used. Retinal tissues from 10 weeks old mice were used.
