title: Maintenance of the synthesis of alpha B-crystallin and progressive expression of beta Bp-crystallin in human fetal lens epithelial cells in culture.
abstract: We have cultured and maintained human fetal lens epithelial cells for several months in primary, secondary, and tertiary culture(s). These cells show unabated synthesis of alpha B-crystallin (alpha B), a lens epithelial cell-specific marker, and progressive expression of beta Bp-crystallin (beta Bp), a major polypeptide of the differentiated lens fiber cells in vivo. Interestingly, the expression of beta Bp was found to be dependent on subculturing of the cells and not on the age of cultures. These observations demonstrate that human fetal lens epithelial cells can be cultured in vitro without the loss of lens specific characteristics and with commitment to differentiation at the biochemical level.
