title: A serum-free defined medium for retinal pigment epithelial cells.
abstract: Human and bovine RPE cells underwent changes in morphology and culture doubling times when passaged in serum-supplemented medium (CM). Furthermore, late passage human RPE cells subcultured in CM medium increased synthesis of three acidic, 43 000-63 000 D proteins. In order to provide a controlled environment for the study of RPE cells in vitro, we have developed a method for growing human and bovine RPE in a serum-free defined medium (DM). RPE cells grown in DM required a 24 h pretreatment with CM to allow the cells to attach and spread on the substrate. Cells grown in DM retained an epithelioid morphology, a stable culture doubling time, and similar 2-D PAGE patterns through several subculturings.
