What is one potential criticism of your fate map data. One potential criticism is that your data are incomplete/inaccurate due to the nature of the fate mapping procedure. You used a fluorescent dye to perform the fate mapping. Labeling cells by adding a dye has a major caveat: you need to ascertain to what extent the dye might be diluted such that you are unable to detect potential progeny of the first labeled cell(s). 4.
