Cell Fate Specification

Cell fate specification is the process by which cells in a developing organism become specialized to perform specific functions. During development, initially similar cells receive signals that guide their development, leading them to adopt distinct identities such as muscle, nerve, or skin cells. This process involves changes in gene expression, which activate certain genes while turning off others. The result is a cell with a unique structure and role, necessary for forming tissues and organs. Essentially, cell fate specification directs each cell on its path to becoming a particular type, ensuring proper development and functioning of the organism.
