If I have a cell array how do I convert it into a single char

If I have a cell array say 1x4 or 1x5. How can I turn it into a single row and single column char without each cell value having double quotes around it.

{'Test1'}    {'Test2'}    {'Test3'}    {'Test4'}

% But I want this in a single column and row char

'Test1 Test2 Test3 Test4'
