The intracellular pH (pHi) of tissue-cultured bovine lens epithelial cells was measured in small groups of 6 to 10 cells using the trapped fluorescent dye 2',7'-bis-(2-,carboxyethyl)-5 (and 6)carboxyfluorescein (BCECF). When perifused at 35 degrees C with artificial aqueous humour solution (AAH) con

β¦ Synopsis
Lens epithelial cells can be kept in their original differentiated state or brought to dedifferentiation depending on the culture conditions. The different stages of differentiation can be identified using specific markers, namely the activity of steroid metabolizing enzymes, and the synthesis of specific structural lens polypeptides. For this reason lens epithelial cells in tissue culture provide a unique system for the study of the regulation of RNA and protein biosynthesis.

The effects of heat, oxidative and osmotic stress on heat shock proteins (HSP-70(I), HSC-70, and HSP-40 of tissue cultured mouse lens epithelial cells (alphaTN-4) were investigated.

Previous studies from our laboratory have led us to conclude that lens cell elongation is caused by an increase in cell volume. This volume increase results from an increase in the potassium content of the cells due to decreased potassium efflux. In contrast, an increase in the volume of most cells
