摘要：
A novel class of agents has been identified to serve as cell-guard agents and/or target-specific supplements to increase cell quality and yield, as well as select for target cell populations. Laboratory experiments have demonstrated the use of cell-guard agents and/or target-specific supplements in the bioprocessing of cells as well as in selecting out a desired cell population. Several potential additive agents (both natural and synthetic) have been identified during these studies, including Vitamin D3, NAC, resveratrol, salubrinal, AKT, and tunicamycin (among others) that hold promise for application in cell models. In one embodiment, hypothermic stress regimes are utilized. In another embodiment, normothermic conditions are utilized while other stressors are tested in the processing. The methods of maintaining mass cell cultures and/or selecting out particular cell populations for further research and clinical use represents an important step in therapeutic discovery. The cell-guard agents are process-matched and cell-matched to protect and/or select particular cells during laboratory and clinical manipulation. The components modulate cell stress and survival pathways.
