how remove from a cell array, the words in an other cell array

Hi, I want to remove from the cell array word (attached), the words in an other cell array word_bis(attached). I have tried

out_str1 = strjoin(word(~ismember(word,stopwords_cellstring)),' ')

but it gives me an error:

Error using cell/ismember>cellismemberR2012a (line 193)
Input A of class cell and input B of class cell must be cell arrays of strings, unless one is a string.

Can you help me to solve the problem? thanks
