Long-term preservation and easy transportation of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) will facilitate their application in medical treatment and bioengineering. A pilot study on the freeze-drying of hBM-MSCs was carried out. hBM-MSCs were loaded with trehalose. The glass transition temperature of the freeze-drying suspension was measured to provide information for the cooling and primary drying experiment. After freeze-drying, various rehydration processes were tested. The highest recovery rate of hBM-MSCs was (69.33±13.08)%. Possible methods to improve freeze-drying outcomes are discussed. In conclusion, the present study has laid a foundation for the freeze-drying hBM-MSCs.
长期保存和便于运输人类骨髓间充质干细胞(hBM-MSCs)将有助于它们在医疗和生物工程中的应用。我们进行了 hBM-MSCs 冻干的初步研究。将海藻糖负载到 hBM-MSCs 中。测量冻干悬浮液的玻璃化转变温度,为冷却和初级干燥实验提供信息。冻干后,测试了各种复水过程。hBM-MSCs 的最高回收率为(69.33±13.08)%。讨论了可能改善冻干结果的方法。总之,本研究为 hBM-MSCs 的冻干奠定了基础。
