Determination and Differentiation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
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.
Show
A committed muscle precursor is already determined before it visibly develops striations and contractile fibers.
Watch for
Determination locks in fate before differentiation shows it outwardly — a determined cell can look identical to undetermined neighbors.
