Fig. (2) Expression of neural progenitor markers in the non-laminated region (ciliary margin-like zone) of the adult human retina. (A) Confocal image of adult human retina showing intense expression of Nestin (green) in the most peripheral region adjacent to the ciliary body (asterisk). Pigmented (solid arrow) and non-pigmented (segmented arrow) ciliary epithelium do not express Nestin in situ [25]. (B) Confocal image of non-laminated anterior retina showing expression of the Müller cell marker CRALBP (green) and the progenitor marker CHX10 (red).
