String Manipulation Syntax

I have a cell array. Column 1 contains a string, and I would like to extract characters 4 through 8 of this column (in each row) and place this in column 10. I understand how to do make column 10 match column 1 with:

fdata(:,10) = fdata(:,1);

but how to I make fdata(:,10) just contain characters 4 through 8 of fdata(:,1)?

Thanks for the the help.
