Over 73 amacrine cell types were identified among over 380K amacine nuclei in the current atlas. These 73 cell types can be categorized into GABAergic amacine cells, Glycinergic amacine 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 73 amacrine cell clusters cound be annotated as known amacrine types.
