Talk:Fate mapping

There seems to be a issue concerning the difference between lineage tracing and fate mapping. The example in the main article is a perfect example of lineage tracing, however, it's not how a fate map is typically done. For constructing a fate map, one neither need to start from the one-cell stage nor follow the product of each mitosis event. Instead, one only need to unambiguously mark either one cell or one homogeneous group of cell at one time point, and recover the progeny of this/these marked cell(s) at a later point, after their migration or differentiation, depending on the purpose of the fate map. A fate map only needs information from two time points. This distinguish it from lineage tracing, which requires progeny after each round of mitosis to be recorded. In fact, lineage tracing could be viewed as a fate map with N time points (N= round of mitosis during observation).

wavelenght wrong

"with an ultraviolet (450 nm) laser" must be misstyped. 450 nm light looks blue to the eye. Please check source. New 405 nm laser (used in blue-ray disk readers) looks violet and is called "UV" these days.
