Accessing cell array data every 2 columns and concatenating them

I have cell array A =

    {1×137 cell}    {1×134 cell}    {1×410 cell}    {1×411 cell}    {1×439 cell}  {1×455 cell}
    {1×137 cell}    {1×134 cell}    {1×410 cell}    {1×411 cell}    {1×439 cell}  {1×455 cell}
    {1×137 cell}    {1×134 cell}    {1×410 cell}    {1×411 cell}    {1×439 cell}  {1×455 cell}

I need to concatenate columns 1 & 2 and 3 & 4 and 5 & 6, so cell array A is 3x3

    {1×271 cell}     {1×821 cell}      {1×894 cell}
    {1×271 cell}     {1×821 cell}      {1×894 cell}     
    {1×271 cell}     {1×821 cell}      {1×894 cell}

The column size within A is not always the same size.

Thank you,

Easy with cellfun:

%generate random data:
A=cell(3,6);x=[137 134 410 411 439 455];
for r=1:size(A,1)
    for c=1:size(A,2)
        A{r,c}=num2cell(randi(10,1,x(c)));
    end
end

%the actual line of code:
A=cellfun(@(x1,x2) [x1,x2],A(:,1:2:end),A(:,2:2:end),'UniformOutput',0);
