Figure 1. ET-1 expression in the anterior segment of human eye
Expression of ET-1 mRNA in human iris, ciliary processes and ciliary muscle by in situ hybridization with DIG labeled antisense probe (A, C, E). Positive ET-1 mRNA signals (blue) were observed in the iris (A), in the CM (C), and in the NPCE and stroma of the CP (C, E). No substantial staining was seen when hybridized with the sense probe (B, D). Abbreviations are used in the figure for iris (I), ciliary process (CP), and ciliary muscle (CM).
