Transmission electron microscopy images of the mouse iris. (A) Telocytes (TC) (blue arrows) and putative stem cells (red arrows) are located between melanocytes in the anterior layer (AL). They are not present in the pigmented epithelial layer (EL) of the iris. Telocytes form a network in the stroma of the anterior marginal layer of the iris. (B) A higher magnification of the blue-square marked area in (A) shows a TC with three telopodes (Tp1-Tp3) extended among melanocytes (M), capillary (cap) and nerve endings (n). (C) Higher magnification of red square marked area in (A) shows a putative stem cell (SC) between M in the anterior layer of iris. PEC: pigmented epithelial cells of the iris. Scale bars: A – 10 μm; B – 5 μm; C – 2 μm.
