how to delete a element out of cell?

Let's say:

A : 1x3 cell class
A={cell_1,      cell_2,        cell_3,     }
A={[2x1 double],[5x1 double],[3x1 double]}
        cell_1      [999;222]
        cell_2      [444;123;2000;789;1000] 
        cell_3      [5000;9000;4000]

I also have matrix:

B=[1000;2000;4000;5000]

Question: How to delete matrix B out of cell A? Let's say:

result : 1x3 cell class
result={cell_1,      cell_2,        cell_3,     }
result={[2x1 double],[3x1 double],[1x1 double]}
        cell_1      [999;222]
        cell_2      [444;123;789] 
        cell_3      [9000]

result = cellfun(@(C) C(~ismember(C, B)), A, 'uniform', 0);
