Cells are the fundamental units of all known living organisms. Humans have an estimated 100 trillion or 1014 cells; a typical cell size is 10 µm; a typical cell mass is 1 ng.


Cells in culture, stained for keratin (red) and DNA (green), with a small breadth between each cell.
A space located or occurring between cells is often referred to as an intercellular space. When the space is passing a cell, or cell membrane or situated beside or between cells the term paracellular space is usually used. Epithelial cells are packed tightly together, with almost no intercellular spaces and only a small amount of intercellular substance.

An intercellular space probably can be reduced to that remaining as one membrane physically touches that of its neighboring cell. But, often cells express transmembrane proteins.
