, but focussed on the
cytoplasmic threads of a cell with small globular extensions. The fluorescence seen here is from
the cell's cytoplasm, and is compared in (

) A zoom of the region in the original image and in (

much improved and the
white arrow points
to one example of a cytoplasmic component that was
resolved in the restored image. The

domain of the restored image
