Internalization of DN-Rac expressing mesoderm cells.
Confocal image series of ppl progenitor cell (green) internalization in a Tg(-4gsc:eGFP-Hsa.HRAS) embryo (5 - 6.5 hpf), overexpressing DN-Rac to inhibit progenitor cell protrusion formation, Lyn-TagBFP to outline the plasma membrane (red), and Dextran-Rhodamin to label the interstitial fluid (blue). Frame rate, ~ 2 fps; 3 min/frame. Scale bar, 20 μm.
