acellular
Lacking cellular structure
Acellular means lacking cells or not made up of cells.
In biology, acellular organisms like viruses have no cellular structure.
Acellular vaccines contain only parts of a pathogen rather than whole cells: the acellular pertussis vaccine.
The term also describes body components without cells, like the acellular layer of certain tissues.
