Immunocytochemical localisation of collagens (I-V) in the human iris.
In this study we investigated the distribution of collagen types I-V in the human iris at the fine-structural level using cryoultramicrotomy and London Resin White plastic embedding. Collagen type I was shown to be present in the basement membrane of iris vessels, in contrast to type III, which was absent; both types I and III were present in the iris stroma. Collagen type IV was a major component of basement membranes of vascular cells, myoepithelial cells, fibroblasts and epithelial cells. Types II and V were absent. Both cryo and plastic embedding techniques produced closely comparable results.
