Developmental Biology is the study of how living organisms grow and develop from a single cell into complex structures. This field explores the processes that guide the formation of tissues, organs, and systems in organisms, including humans. Researchers in this area examine how genes, cells, and environmental factors interact to shape development, helping us understand everything from embryonic development to regenerative medicine. By studying model organisms like fruit flies and zebrafish, scientists can uncover fundamental principles of development that apply across many species. This knowledge is crucial for advancements in medicine, such as understanding congenital disorders and improving tissue engineering techniques.
