Objective To culture astrocytes of human optic nerve and establish the cell lines for further study of healing process after optic nerve trauma. Methods Astrocytes of infantile optic nerve were cultured by tissue inoculation or tissue digestion with 0.25 % trypsin and 0.06% EDTA. The second and fourth passage cells were stained with HE and anti-GFAP, S-100 protein, vimentin, and CD34 antibodies. Results The trypsinized astrocytes of infantile optic nerver eached confluence in 7 days. The cultured cells were in polygonal shape with processes and the cytoplasm was abundant. These cells were positive in GFAP, S-100 protein and vimentin staining, and negative in CD34 staining. Conclusions Astrocytes of human optic nerve can be successfully cultured by trypsinization rather than tissue inoculation. (Chin J Ocul Fundus Dis, 2001,17:144-146)
