Determination and Differentiation
Captions available
The idea
Determination commits a cell irreversibly to a fate before any visible change; differentiation is the later process where that committed cell actually specializes in structure and function.
In practice
A committed muscle precursor is already determined before it visibly develops striations and contractile fibers.
Where people slip
Determination locks in fate before differentiation shows it outwardly — a determined cell can look identical to undetermined neighbors.
