An embryo is an early developmental stage of multicellular organisms. In humans, it refers to the period from fertilization until the end of the eighth week of pregnancy, after which the term changes to “fetus.” During the embryonic stage, a rapid series of divisions and transformations occur as the single-celled zygote evolves into a complex structure with distinct layers of cells that will form the various tissues and organs of the body. This process includes cell division, migration, and differentiation, as well as the development of essential body structures such as the spinal cord, heart, and limbs. Embryology, the study of embryos, is crucial for understanding genetic development, congenital abnormalities, and the impact of environmental factors on early development. Additionally, research on embryos, including the use of stem cells derived from them, holds significant potential for regenerative medicine and therapeutic interventions.
