# s-gst: they take decisions in a way that is not necessarily uniform (jazzy? funky? fuzzy?)

AA << found that fate decision is not a unique programmed event, but the result of a very dynamic process composed of spontaneous fluctuation and selective stabilisation of alternative cellular states >>

<< The whole process is reminiscent of trial-and-error learning in which each cell explores—at its own rhythm and independently of cell division—different molecular possibilities (i.e. different genes turned on or off) before reaching a stable combination of active genes and the corresponding morphology >>

AA << observed that some cells seem to "hesitate" and change morphology many times before reaching a stable state >>

Which type of cell to become: Decision through indecision.

<< Individual cells take lineage commitment decisions in a way that is not necessarily uniform >>

AA << identifies a new category of cells with fluctuating phenotypic characteristics, demonstrating the complexity of the fate decision process >>
