Check the below demo code.
% Generate random cells
cell1 = cell(10,1) ;
cell2 = cell(100,2) ;
for i = 1:size(cell1,1)
cell1{1} = rand(3,1) ;
end
for i = 1:size(cell2,1)
for j = 1:size(cell2,2)
cell2{i,j} = rand(10,1) ;
end
end
% GEt common
iwant = cell(size(cell2)) ;
for i = 1:size(cell2,1)
for j = 1:size(cell2,2)
for k = 1:size(cell1,1)
c = ismember(cell1{k},cell2{i,j}) ;
end
end
end

iwant = [C(idx) c2(idx,2:end)] ;

I am certain we've answered similar questions from you in the past. By now, you should also know that pictures are useless for us and that actually attaching an example of your data is a lot more useful.
With cell arrays, you can use intersect to find which elements overlap between your two columns arrays. It's then trivia to construct your output from the 2nd and 3rd output argument of intersect.
Even easier, would be to convert your cell arrays to tables. The whole operation is then simply a call to innerjoin:
innerjoin(cell2table(UD1), cell2table(whateverthatothercellarrayisnamed), 'Keys', 1)

In case you haven't noticed, I also gave you a very simple way to achieve what you want. Just one line of code needed:
innerjoin(cell2table(UD1), cell2table(whateverthatothercellarrayisnamed), 'Keys', 1)
