Anterior and posterior tissues of the human eye. (A) Diagram of the human eye and the optic nerve, depicted in sagittal cross-section. Structures represented in the ocular cell atlas are labeled. (B) Section of the optic nerve head (ONH) and surrounding tissues immunostained for myelin basic protein (MBP, red) and beta-tubulin (TUBB3, green). TUBB3 highlights bundles of axons in the retina and ONH, and MBP highlights myelinating oligodendrocytes in the optic nerve (ON). The scale bar shows 100 µm. PPS, peripapillary sclera; RPE, retinal pigment epithelium; Cho, choroid.
