Cell sorting in heterotypic cultures of ectoderm and mesoderm progenitors.
Confocal image series of cell sorting in heterotypic aggregates consisting of ectoderm and mesoderm progenitor cells cultured for 4.5 h. All cells express Lyn-VenusGFP to outline the plasma membrane (green). Ectoderm progenitor cells were additionally labelled with cytoplasmic Dextran-Alexa648 (red). Frame rate, 6 fps; ~ 3min/frame. Scale bar, 50 μm.
