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.
As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues. There are no anatomical molds shaped like lungs, livers or other tissues for cells to grow into. Rather, ...

The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support Center at the Medical Research Institute of Kanazawa Medical University has identified eleven novel ...

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 ...
