Clean up figure and move to white-background cell images
Details
Get rid of the black boxes with white Xs; lack of data is better conveyed by a simple white space. The faint magenta cell membrane label on the black background is very, very hard to see; I recommend that (essentially all) images be presented on a white background instead, like in Fig. 1.
