What is an embryo?

Career: Embryo

Embryos are early developmental stages of multicellular organisms. In humans, an embryo refers to the stage of development from fertilization until the end of the eighth week, after which it is called a fetus. During this time, the basic structures and organs of the body begin to form. Embryos are studied in various fields such as medicine, biology, and reproductive technology, particularly in contexts like in vitro fertilization (IVF) and stem cell research.
