Outline of Final Research Achievements

Although cell division is a well-known physiological event and historical target of biological research, the molecular mechanisms remains poorly understood area of biology. Quantification of the microtubule dynamics in 3D is a key to reveal the mechanisms. However, due to the physical constraints of samples or the microscope objective in the 3D, conventional microscopes are not suitable for 3D analysis of microtubules. We solved this problem by attaching Electrically tunable lens (ETL) to the microscope and using the ETL as a focusing device.
By using our system, we measured the microtubule dynamics in mitosis and acquired quantitative data. The mean value of growth speed at 3D was statistically faster than the 2D result, on the other hand, there was no significant difference between the lifetime of at 3D analysis and 2D analysis because of the quick bleach of fluorescent proteins.
We are planning to improve the experimental method to achieve long time analysis of the microtubules.
