Many developmental signals are associated with changes in proliferative response. Also, growing organs and tissues can contain different cellular subpopulations with a defined status in the cell cycle, e.g., quiescent in stem cells, high proliferation in progenitors, cell cycle exit in differentiating cells. This chapter describes a method for isolation of individual cell populations from the Xenopus tadpole brain and determination of their cell cycle status using flow cytometry.
