Fig. 4: Cone cell cluster identification and CG5597 is a novel marker for adult cone cells.

a Cone cell cluster (CC, arrow) in Seurat UMAP cluster plots of 7-day-old adult eyes are colored red. b–d FeaturePlots showing expression of ct (b), Crys (c), and CG5597 (d). All expressing cells are brought to the front. Red arrows point to the cone cell clusters. e Schematic of an ommatidium showing the position of the tangential view shown in (f) and coronal view shown in (g). f, g Immunostaining images of a CG5597-T2A-Gal4 > UAS-mCherry-nls 7-day-old adult eye costained with Ct and Elav with coronal view shown in (f) and tangential view shown in (g). Scale bars: 10 μm.
