Developmental biology is the branch of biological sciences that investigates the processes by which organisms grow, differentiate, and acquire their form from fertilization to adulthood and often through regeneration and aging. It integrates molecular genetics, cell biology, genomics, and systems biology to elucidate mechanisms such as cell fate specification, pattern formation, morphogenesis, and organogenesis. Developmental biology examines regulatory gene networks, signaling pathways (e.g., Wnt, Hedgehog, Notch, TGF-β), epigenetic modifications, and mechanical forces that coordinate spatial and temporal control of gene expression and cellular behavior, providing a framework for understanding congenital disorders, tissue regeneration, and evolutionary changes in body plans.
The complex 3D shapes of brains, lungs, eyes, hands, and other vital bodily structures emerge from the way in which flat 2D sheets of cells fold during embryonic development. Now, researchers at Columbia Engineering have ...
