Diagram illustrating the cryopreservation of lung organoids in various stages of growth or preparation. Lung tissue fragments can be used to directly derive stem cells or instead cryopreserved and used later as a source of stem cells. These stem cells can either be cryopreserved or used to develop organoids, which can then either be used in experiments or cryopreserved themselves for convenient use at a later date.
