How to concatenate lines in cell arrays

Hi,
I have a Cell array, name DATA with 5*50 cells. Each cell has a 1000*30 matrix
I would like to obtain a new matrix that contains the concatenation of the column 1 and all lines (:,1), for all the 50 columns. I need all the lines of all cells in all columns to show up as a resulting matrix, named MR, of dimensions 40000*50.
Right now I have the following code:
for j=1:1:50
MR(:,j)=cat(1,DATA{1,j}(:,1),DATA{2,j}(:,1),DATA{3,j}(:,1),DATA{4,j}(:,1),DATA{5,j}
end
However, the code write all the columns with the same values, so definitely there is something wrong with it. Any help is appreciated.
Best regards,

So you have a {5 x 50} cell array containing [1000 x 1] vectors. Then I still do not understand, how you can obtain a [40000 x 50] matrix.
