Treat
A limited term (< 24 hour) addition of a special medium, small molecules or growth inhibitors applied to adherent or suspension cells to affect some change.
The Treat action can be used in conjunction with a Feed action or as a stand alone action.

The Treat action continues the vessels in the action group, does not require new vessels, nor does in create a new Culture Track.
