Converting 2D cell array to 3D matrix

I have a cell that is [8x454] with each element in the cell containing a [900x1] matrix. I would like to convert this cell into a 3 dimensional matrix of size [8x454x900]. Ive tried some things including reshape, cat and permute but can never seem to get it right. Any help would be greatly appreciated!

E.g.,

MyCell = repmat({(1:4)'},2,3) % small sample data

MyCell = 2×3 cell array
    {4×1 double}    {4×1 double}    {4×1 double}
    {4×1 double}    {4×1 double}    {4×1 double}

[m,n] = size(MyCell);
reshape(cell2mat(MyCell(:)').',m,n,[])

ans = 
ans(:,:,1) =

     1     1     1
     1     1     1


ans(:,:,2) =

     2     2     2
     2     2     2


ans(:,:,3) =

     3     3     3
     3     3     3


ans(:,:,4) =

     4     4     4
     4     4     4

size(ans)

ans = 1×3

2 3 4

cell2mat(reshape(YourCell, 1, 1,[]))
