Abstract
A method of preparing a fat graft includes introducing fat tissue into an internal chamber of a vessel of a cell or tissue isolation, purification, and storage device through a first opening of the vessel. The method also includes introducing an amount of a wash solution effective to wash the fat graft or an amount of a cryoprotectant effective to cryopreserve the fat graft into the internal chamber of the vessel through a second opening of the vessel and mixing the fat tissue with the wash solution or the cryoprotectant. The method further includes either: when wash solution is introduced, centrifuging the device containing the fat graft to separate the fat graft from the wash solution and drawing the wash solution from the first end of the device; or, when cryoprotectant is introduced, cooling the fat graft to a temperature below 0° C.
