Method Cell volume was estimated by analysis of microscopic images recorded every each five cell divisions during a routine procedure of determination of replicative lifespan. Images were captured with a Nikon Eclipse E200 microscope with 20× objective, equipped with a Sony digital camera. Diameter of the cell was measured using a MicroImage 3.0 software. Cell diameter (d) was measured in four times in various planes for each cell and the mean value was used for calculations. It was assumed that each cell has a regular shape similar to a sphere and the cell volume was calculated as 4/3p(d/2)3.
Comments In a population, cells cease to bud after various number of cell cycles. The ratio of volumes of the bud and the mother cell in the wild-type strains studied was 0.50–0.70 in the first budding decreasing to about 0.28 in the last buddings.
