Confocal light micrograph of a mouse embryo at the eight-cell stage. These cells, each called a blastomere, have divided from a single fertilised cell (zygote). The blastomeres have started to undergo compaction, a process where adjacent cells form tight junctions. This changes the embryo from a loose cluster of spherical cells to a tightly-packed mass. Important for this step is the establishment of polarity. Here, Par6, which indicates the apical pole of a cell has been labelled purple. Also labelled is actin (green), one of the components of the cell cytoskeleton, highlighting microscopic cell surface structures and cell-cell contacts. | |
