The bleached spot is located near the center of the image as indicated by an arrow. When the first bleached spot disappeared, a new spot was created at the same place to allow continuous tracking. Bleached spot continues to move toward the center of the cell, although the phenomenon was observed in only a fraction of cells at the time. Research 20 years later suggests that the variability may be related to mechanical signals (see Guo and Wang, 2008). Recording time, 19 min (upper) and 20 min (lower). |
