Cell lineage analysis of the amphipod crustacean Parhyale hawaiensis reveals an early restriction of cell fates

In the amphipod crustacean, Parhyale hawaiensis , the first few embryonic cleavages are total and generate a stereotypical arrangement of cells. In particular, at the eight-cell stage there are four macromeres and four micromeres, and each of these cells is uniquely identifiable. We describe our stu...
