The cultured retinal Müller cells were identified by immunocytochemistry using antibodies against the Müller cell markers GS and vimentin, which is a cytoskeletal intermediate filament protein in Müller cells. The nuclei were stained with DAPI. Almost all cells were positive for GS and vimentin (A). The negative controls are shown in B. To access the data, click or select the words “Appendix 1.”
