Identification and Confirmation of DCX as a DS-RGC Marker
(A–C) DCX was highly co-localized with (A) FSTL4, while its co-expression with pan-RGC markers (B) BRN3 and (C) SNCG demonstrated less correlation.
(D) Quantification of immunocytochemistry results indicated that DCX expression correlated with 82.48% ± 1.66% of FSTL4-positive RGCs, while it was identified in subsets of BRN3- and SNCG-positive RGCs at 42.61% ± 1.88% and 53.57% ± 1.88%, respectively.
(E) Single-cell RNA-seq values demonstrate expression of DCX correlated with other DS-RGC markers, but was found exclusive of markers of other RGC subtypes and retinal cells.
