From: Pak2 reduction induces a failure of early embryonic development in mice
Subcellular localization of Pak2 in early mouse embryos. Zygotes; pronuclear-stage, 2-cell, 4-cell, and 8-cell embryos; and blastocysts were labeled with a Pak2 antibody (green) and counterstained with propidium iodide (PI; red) to visualize DNA. Arrowheads indicate the accumulated Pak2 signal. Scale bars, 20 μm; Pak2, p21-activated kinase 2
