Figure Lengend Snippet: (A, C) Expression of Müller glia marker Glast , retinal pigment epithelium (RPE) marker RPE65 , and Vim in a homeostatic retina and regenerating (28 dpi) contralateral retina; (A) was then probed for Hes1 and (B) for Hes5 . (B) Expression of Hes1 and other Notch pathway genes, receptor Notch1 and ligand Jag1 , in the same retinal tissue section as in (A). Hes1 is expressed in Müller glia in a homeostatic retina. (D) Expression of Hes5 and other Notch pathway genes, Notch1 and Jag1 , in same tissue sections as (C). (E-E’) Proportion of rod photoreceptors in regenerated (101 dpi) retinas after they were treated with either vehicle or Notch inhibitor DAPT at 15 dpi. (F-F’) Proportion of Müller glia in regenerated (101 dpi) retinas after they were treated with either vehicle or Notch inhibitor DAPT at 15 dpi. Asterisks indicate cells expressing a gene, and arrowheads indicate autofluorescence. Scale bar is 50 μm.
Article Snippet: DAPT treatment: we soaked small pieces (>0.5mm in diameter) of cotton balls (Thermo Fisher) in 100 mM Notch pathway inhibitor DAPT (Tocris) or its vehicle dimethyl sulfoxide (DMSO; Sigma).
