title: Temporal coordinates: the genes that fix cell fate with birth order.
abstract: Drosophila neuroblasts sequentially express a set of four transcription factors that specify the fates of their progeny according to the successive order of their generation. In analogy to spatial coordinate genes that specify neuroblasts by position, these sequentially expressed genes can be called "temporal coordinate genes."
