Over 89 amacrine cell types were identified among over 571K amacrine nuclei in the current atlas. These 89 cell types can be categorized into GABAergic amacrine cells, Glycinergic amacrine cells, and Both type using marker genes, specifically the GABA-synthetic enzymes GAD1 and GAD2, and the glycine transporter SLC6A9. Based on previously characterized markers, 14 of the 89 amacrine cell clusters could be annotated as known amacrine types.
