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.
Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery networks. Lumens in the pancreas form a complex ductal system, and its channels transport digestive ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the uterine wall—pausing pregnancy until she senses that her fat reserves are aligned with the season. This ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...
