Immunohistochemical markers for retinal gliosis.

Immunohistochemical marker	Cell of interest	Staining characteristics
Glial fibrillary acidic protein (GFAP)	Astrocytes and Müller cells	Positive for reactive Müller cells
Ionized calcium binding adaptor molecule 1 (Iba-1)	Microglial cells	Negative
Oligodendrocyte lineage transcription factor 2 (Olig 2)	Oligodendrocytes	Negative
S100	Schwann cells and astrocytes	Positive for astrocytes, not cells of interest
Neuron-specific enolase (NSE)	Neuronal cells	Positive for extracellular optic nerve fibers
Ki67	Cell proliferation	Negative
Vimentin	Mesenchymal cells	Positive for Müller cells only
