The reason for the serum is so when thawing the cells they are not going to be starved of nutrients and it also acts as a cushion for the cells during the thawing process depending on the amount of time it takes to take the thawed vial of cells to reach a culturing plate in fresh medium. Because DMSO is toxic to the cells in an extended amount.
