Embryonic development is the process by which an embryo develops from a fertilized egg into a fully formed organism. It involves complex genetic, cellular, and molecular processes that are highly regulated and coordinated. Embryonic development requires specialized skills and knowledge, including a deep understanding of genetics and developmental biology, as well as techniques such as in vitro fertilization, embryo culture, and genetic manipulation. Researchers in the field of embryonic development work to uncover the underlying mechanisms that drive embryo growth and differentiation, in order to better understand human development and disease.
