garland nephrocyte differentiation

The process in which a relatively unspecialized cell acquires the specialized structural and/or functional features of a garland nephrocyte. A garland nephrocyte is an insect renal cell that filters hemolymph and forms a ring with other garland nephrocytes around the esophagus. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
