Abstract: The invention provides cryopreserved compositions of cells, wherein the compositions are advantageously in the form of self-sustaining bodies that can be individually handled and combined independently of a container, allowing for easy customization of the eventual pooled preparation. The invention also provides pre-pooled stacks of the self-sustaining cryopreserved compositions for eventual thawing to produce pooled preparations of cells. A mold and methods for forming the self-sustaining bodies are also provided. The invention is also concerned with methods of forming pooled preparations of cells using single-cryopreserved compositions of cells.
