Auszug aus dem Buch
Development of a program to analyse and visualize ciliary beat frequency ex vivo
A main topic in lung research is to understand the mechanisms that continuously clean the airways from inhaled particles by transport of mucus. This transport is maintained by the continuous beating of cilia that are present on airway epithelial cells. To date, the beat frequency of individual ciliated cells is measured as an indicator of mechanical clearance activity. However, the present frequency analysis was, due to many constraints, very time consuming, inflexible, limited in features and very error prone. The main task of this work was the improvement of the analysis tools to analyze ciliary beat frequency. This was performed by the development of an encapsulated program environment, which was implemented with Matlab (The MathWorks, Inc.). The new program improved the analysis of ciliary beat frequency of individual cells but also generated a tool that allows to visualize the changes in ciliary beat frequency of all cells present in the microscope field of view opening up new possibilities for analysis.
