The cellome is the whole set of biological entities within cells and their interactions in the cell, and the totality of biological cells. They are both physical and informational. Proteins are major components of the cellome. The cellome concept is derived from the understanding that cells as a whole, rather than simply their DNA or RNA, can be used for therapeutic purposes. As a distinct group concept, cellome refers to cells and their genetic materials kept as a resource for biotechnology.
Cellomics is the study of the cellome.
