Human Embryo and Sperm It looks like the world at war, but it is actually five days after the fertilisation of an egg, with some remaining sperm cells still sticking around. This fluorescent image was captured using a confocal microscope. The embryo and sperm cell nuclei are stained purple while sperm tails are green. The blue areas are gap junctions, which form connections between the cells.
