d ={'gene1' [] 'u' 'u' 'd'
'gene2' 'u' 'u' [] 'u'
'gene3' [] 'u' 'd' []
'gene4' 'd' 'u' 'd' 'd'}
out = cellfun(@(x)x(~cellfun(@isempty,x)),num2cell(d,2),'un',0);

No, you are trying to create a cell array with a variable number of columns per row. That is not allowed.
The closest you would be able to get would be to change to a cell vector, one entry per row, each entry of which contained a cell vector, the entries of which were the strings. e.g.,
YourVector{3} = {'gene3' 'u' 'd'}
