Blastocisztává

Blastocisztává is a term of Hungarian origin used in embryology to describe a stage of early embryonic development. It refers to the blastocyst, a structure formed in the early development of mammals. The blastocyst is a hollow ball of cells, approximately 5 to 9 days after fertilization in humans. It is characterized by an outer layer of cells called the trophectoderm, which will later contribute to the placenta, and an inner cell mass, which will develop into the embryo itself. The cavity within the blastocyst is known as the blastocoel. The formation of the blastocysteve is a crucial step in implantation, the process by which the embryo attaches to the uterine wall. This stage follows the morula stage, where the embryo is a solid ball of cells, and precedes the gastrulation stage, where germ layers begin to form. Understanding the blastocysteve is fundamental to the study of reproductive biology and assisted reproductive technologies.
