    Two measures will be taken by our labs in an attempt to spread FSM as a routine mode of light microscopy.First, protocols are under development to generate cell lines that permanently express low levels of Citrulline uorescent cytoskeleton proteins optimized for speckle image formation.This will avoid the timeconsuming steps of microinjection and the tweaking of transient expression of uorescent protein and will turn FSM into a robust technique with high quantitative reproducibility.Second, the qFSM software package will be released.The use of cell lines with reproducible levels of uorescent protein will greatly aid the software distribution.Under standardized conditions many of the processing steps can be furnished with default control parameters so that meaningful results can be obtained without indepth knowledge of the mathematical algorithms.Last, the idea of FSM will be promoted by more applications outside the cytoskeleton eld.The analyses of FA dynamics make an initial step in this direction.Sheetz, Julia E.
