Sample Preparation:

Sampleprep ID:	SP000186
Sampleprep Summary:	After 48 h of continuous rocking, the spheroids were washed with SFM at room temperature. The culture medium was changed to the cold storage medium (UW alone, UW + 1 mM Def; SFM alone; SFM + 1 mM Def; SFM + 1 mM Def + 1 ?M CsA; SFM + 1 ?M CsA) at room temperature. Spheroids were left in rocked culture without cold storage as control. Spheroids intended for cold storage were rocked in glass dishes (10 × 8 × 2 cm) custom-made by Mayo Division of Engineering and siliconized with Sigmacote for 30 min and then transferred into 50-ml conical tubes (BD Falcon; 1 × 106cells/ml, 20 ml in total) and put on ice for 1 h. Of note, spheroid box and glass dishes differ in size (i.e., volume capacity) but possess similar properties of spheroid formation and culture. Finally, tubes of spheroids were placed in a refrigerator to be cold stored at 4°C. After 24 or 48 h of cold storage treatment, the spheroids were centrifuged at 50 × g for 5 min, and the supernatant fluid was removed. Warm SFM (20 ml) at 37°C was added to each tube. The tubes were mixed gently prior to adding 20 ml of cell suspension to each glass culture dish and continued to rocking culture. Cultures were maintained in a humidified incubator at 37°C with a 5% CO2 atmosphere.
