A Transgenic Method to Measure Mitotic Exit in Drosophila Embryos.

Mitotic exit is a necessary step for highly specialized cells to terminally differentiate and acquire unique functions. The FUCCI system can be used to visualize mitotic and post-mitotic cells during development and regeneration in both live organisms and fixed tissues. Here we describe a Fly-FUCCI protocol for assaying mitotic exit in Drosophila embryos.
