I think after completing the entire cell cycle the new daughter cells will have 24 chromosomes. This is can be explained by the fact that the type of cell division that took place is mitosis. Mitosis takes place in all the body cells where a parent cell divides to yield daughter cells with the same number of chromosomes, and so will do the kidney cells. The other type of cell division (meiosis) only takes place in the germ line cell to make gametes.
