title: Comparison of pulmonary endothelial cell and fibroblast proliferation using time-lapse cinematographic analysis.
abstract: Time lapse cinematography was used to study and compare the proliferation and migration activity of pulmonary endothelial cells and fibroblasts, two cell types with very different structural and functional properties. Endothelial cells were found to have a more rapid growth rate than fibroblasts. Contributing to the shorter population doubling time of the endothelial cells were lower interdivision times and a tendency for these cells to remain in division cycle with successive generations of growth. Striking differences between endothelial cells and fibroblasts were seen in migration behaviour. Endothelial cells had lower migration rates and tended to remain within a restricted growth area, whereas fibroblasts migrated freely throughout the growth area.
