1. An anti-lesion storage method for cells comprising:
adjusting a partial pressure of carbon dioxide in a suspension medium containing cells, the cells comprising platelets or a platelet concentrate, with 30 mmHg or 50 mmHg;
placing the platelets or the platelet concentrate in a collection device; and
placing the collection device in a three-gas storage apparatus,
wherein:
a volume fraction of carbon dioxide in the three-gas storage apparatus is controlled to be 3.5%,
a volume fraction of oxygen in the three-gas storage apparatus is controlled to be 17%,
a storage condition in the three-gas storage apparatus is controlled to a temperature between 2-24° C., such that, when the temperature is between 2-17° C., the storage condition corresponds to a standing storage condition, and when the temperature is between 18-24° C., the storage condition corresponds to a shaking storage condition.
