The invention relates to a methods and uses for the preservation of stem cells, by a method comprising the steps of combining the stem cells with a cryopreservation medium to produce a mixture, and freezing the mixture to produce a frozen stem cell product, optionally, wherein the method further comprises the steps of thawing the frozen stem cell product, transferring the thawed cells to a storage medium, and storing stem cells in the storage medium,wherein the cryopreservation medium and/or the storage medium comprises a recombinant yeast-derived serum albumin preparation, more preferably wherein the recombinant yeast-derived serum albumin preparation is present in the cryopreservation medium and is also present in the storage medium. The invention also relates to methods and uses for the preservation of stem cells, by a method comprising storing stem cells in a storage medium, wherein the stem cells have been frozen in a cryopreservation medium, thawed, and then transferred to the storage medium prior to st
