False-colour SEM of embryo at the morula stage
Embryo development. False-colour scanning electron micrograph of an embryo at the early stage known as the morula. The egg reaches this phase about 4 days after fertilisation after a series of mitotic divisions. At this stage about 12-16 cells are present and are surrounded by a thin glycoprotein layer, the zona pellucida, which was here removed. The inner cells of the morula will give rise to the tissues of the embryo while the outer cells, covered here by microvilli (tiny orange ridges), will form the placenta. The morula will implant into the uterus six days after fertilisation. Magnification: x645 at 6x7cm size. Magnification: x1005 at 4x5 inch size. This is a mouse morula

EDITORS COMMENTS
This print showcases the intricate details of an embryo at the morula stage, providing a fascinating glimpse into early stages of development. Through false-colour scanning electron microscopy, we are able to witness the remarkable process of cell division and differentiation. At this particular stage, approximately four days after fertilisation, the morula consists of 12-16 cells enveloped by a delicate glycoprotein layer called the zona pellucida. In this image, the zona pellucida has been meticulously removed to reveal both inner and outer cells. The inner cells hold immense potential as they will eventually give rise to various tissues within the developing embryo. The outer cells depicted here are adorned with microvilli – tiny orange ridges that provide additional surface area for nutrient absorption. These specialized structures indicate their crucial role in forming the placenta, which is vital for nourishing and supporting fetal growth during pregnancy. Through magnification at x645 (6x7cm size) or x1005 (4x5 inch size), we can truly appreciate the intricacies of embryonic development on a microscopic level. This specific image captures a mouse morula; however, it serves as an invaluable representation of early-stage embryo development across species. Science Photo Library presents this awe-inspiring photograph as part of its extensive collection featuring subjects like human body, embryo development, cell division, and microscopic photos.
