Immunohistochemical characterization of the chick marginal retina

Abstract: The retina is a highly differentiated tissue with a complex layered structure that has been extensively characterized. However, most of the previous studies focused on the histology of the central retina while little is known about the cellular composition, organization and function of the marginal retina. Recent research has identified a subpopulation of multipotential progenitor cells in the marginal regions of the retina, closest to the ciliary body ("ciliary marginal zone"). These cells are capable of diff… Show more

“…The IPL also showed a large punctate labeling pattern with this antibody. The anti‐calretinin antibody showed cellular labeling in the INL, probably amacrine cells (Acosta et al, ; Lima et al, ), and also a punctate labeling pattern in the IPL (Fig. B).…”

“…Another study in reptiles examining the adult retina of anoles, queen snakes, garter snakes, painted turtles and snapping turtles show that all have an expression of the multipotent progenitor markers, Pax6 and Sox9 , in cells at the margin, but only turtle retinal margins have PCNA+ proliferating cells [ 17 ]. Comparatively, birds, including chicken and quail, both show an active proliferating pool of cells at the CMZ as they can be labelled with BrdU and also positively label with progenitor markers, such as Chx10 , Pax6 and PCNA [ 18 , 19 , 20 , 21 ]. These studies highlight that different species exhibit some shared CMZ characteristics, but proliferation varies widely, especially with the increasing age of the organism.…”

“…At terminals of cholinergic neurons, acetylcholine (ACh) is synthesized from choline and acetyl coenzyme by the cytoplasmic enzyme ChAT, and subsequently ACh is transported into synaptic vesicles by VAChT (Oda 1999). At present, commercially available antibodies against the human VAChT and ChAT proteins are used for studies with mammalian specimens, and distribution patterns of these proteins in cholinergic neurons including amacrine cells in the retina have been described (Bhagwandin et al 2006;Lima et al 2007;O'Donnell & Puri 2010). However, these antibodies do not cross satisfactorily with chicken specimens (T. W and Y. T, not shown).…”
