Storage of ASCs. a Cell viability was measured every hour, while ASCs were stored for 5 h in 3 different suspensions: 1% HA, 20% HA or 20% HuS at either RT or 4 °C. b Visual observation of cells stored in 3 mentioned storage media at RT. c ASCs from all storage conditions were seeded in culture flasks. Morphology and cell attachment ability of ASCs was evaluated after 24 h under a microscope. Representative phase contrast images at ×10 magnification. HA human albumin, HuS human serum, RT room temperature
