  Liquid migration in active soft solids is a very common phenomenon in Nature
at different scales: from cells to leaves. It can be caused by mechanical as
well as chemical actions. The work focuses on the migration of liquid provoked
by remodeling processes in an active impermeable gel sphere. Within this
context, we present a consistent mathematical theory capable to gain a deep
understanding of the phenomenon in both steady and transient conditions.
