How to combine two cell arrays?

I need to combine two cell arrays:

cellarray1= {'P'}    {'A'}    {'Pi'}    {'Ab'}    {'Pa'}

and

cellarray2={'e'}

I want to make this cell array:

newcellarray= {'e','P','A','Pi','Ab','Pa'}

I used:

{{'cell_combination'},cellarray1(1:end)}

but did not work. any suggestion?
