The abembryal pole is a term used in embryology and biotechnology to designate the point of development that is located between the blastocyst and the attachment to the endometrium. This place is the starting point for the proper functioning of the embryo and the development of pregnancy. The blastocyst reaches the ambryal pole a few days after fertilization, then develops rapidly and reaches the uterine cavity before implantation.
According to some scientists, the ambryal pole occupies a special place in the development of the zygote and is associated with some important processes, such as the regulation of the shape and size of the blastula. For example, attaxia of blastomeres at the ambryal pole can influence the formation of bilateral symmetry of the blastura, which subsequently affects its size and shape. Likewise, mutations at this level can lead to abnormalities and delays in embryonic development.
The importance of the ambemryal region for the successful development of the embryo is not limited only to changes in the shape of the blastula, but also relates to other important processes. In particular, the presence of retiluminum and cationic type molecules on ambebral cells may play an important role in the production and storage of yolk, and also regulate cell movement during adulthood. In general, the study of ambryonic processes allows us to better understand the development of embryos and can be used in biotechnology, molecular biology, genetics and obstetrics.
