My definition of a cellular signal is any substance or process which occurs
between two cells  which results in a specific cellular response from one of
the cells.  For example, the release of a cytokine by one cell, which is
taken up by a second cell, resulting in a specific response from the second
cell.  I don't know if I've ever seen the term defined.  I'd be interested
to know.
