摘要： The present invention generally relates to devices and methods for the preservation of cells using drying, freezing, and other related techniques. In one set of embodiments, the invention allows for the preservation of cells in a dried state. In another set of embodiments, the invention allows for the preservation of cells within a glass or other non-viscous, non-frozen media. In some embodiments, the invention allows for the preservation of cells at temperatures below the freezing point of water, and in some cases at cryogenic temperatures, without inducing ice formation. The cells, in certain embodiments, may be preserved in the presence of intracellular and/or extracellular carbohydrates (which may be the same or different), for example, trehalose and sucrose. Carbohydrates may be transported intracellularly by any suitable technique, for example, using microinjection, or through non-microinjected methods such as through pore-forming proteins, electroporation, heat shock, etc. In certain instances, the glass transition temperature of the cells may be raised, e.g., by transporting a carbohydrate intracellularly. In some cases, the cells may be dried and/or stored, for example, in a substantially moisture-saturated environment or a desiccating environment. The cells may also be stored in a vacuum or a partial vacuum. The cells may be protected from oxygen, moisture, and/or light during storage. In certain cases, an inhibitor, such as a cell death inhibitor, a protease inhibitor, an apoptosis inhibitor, and/or an oxidative stress inhibitor may be used during preservation of the cells. The cells may be stored for any length of time, then recovered to a viable state, e.g., through rehydration, for further use.

摘要： A method for cryopreserving cells entails the liposomal delivery of intracellular sugar(s), such as trehalose, sucrose, raffinose, stachyose, and combinations thereof, into cells and tissues, such as red blood cells, for enhancing post-thaw viability. This method enables rapid and easy delivery of protective molecules into cells which thus greatly simplifies the preparation of cells for cryopreservation. Furthermore, as much lower concentrations of intracellular protectant are used, the method allows red blood cells containing the liposomally-delivered intracellular sugar to be transfused into a patient immediately following the thaw without having to first remove any of the cryoprotectant sugar.
摘要翻译：用于冷冻保存细胞的方法需要将细胞内糖（例如海藻糖，蔗糖，棉子糖，水苏糖及其组合）的脂质体递送到细胞和组织例如红细胞中，以增强解冻后的活力。该方法能够将保护性分子快速且容易地递送到细胞中，从而大大简化了用于冷冻保存的细胞的制备。此外，使用更低浓度的细胞内保护剂，该方法允许含有脂质体递送的细胞内糖的红细胞在解冻后立即输入患者，而不必首先除去任何冷冻保护剂糖。
