I was looking for the importance of fate maps so I did some normal google.book search and found the following two importance of fate maps-
1. They helped establish the idea that communication between different parts of an embryo leads to the formation of new cell types and have thus helped discover different signalling pathways.
2. They enable us to interpret experiments in which cells of the embryo are exposed to conditions that may alter their developmental fate.
But I don't know how to find some experiments in which fate maps were really helpful in the mentioned ways.Besides are there other ways in which fate maps have helped our understanding of development? I'll be really grateful if you could tell me, how and where do I look for some sample experiments ?
