In the article,“Characterization of an In Vitro Model of Elastic Fiber Assembly,” by B.W. Robb et al. (Mol. Biol. Cell [1999], 10, 3595–3605), the immortal ciliary body pigmented epithelial (PE) cells were derived from bovine eyes and not human eyes as stated in MATERIALS AND METHODS. An additional reference for these cells is: Helbig, H., Korbmacher, C., Stumpff, F., Coca-Prados, M., and Wiederholt, M. (1988). Na+/H+ exchange regulates intracellular pH in a cell clone derived from bovine pigmented ciliary epithelium. J Cell. Physiol. 137, 384–389.
