移植用微囊化神经细胞 /组织制备及运输的实验研究

Experimental study of microencapsulated nerve cell/tissue for transplantation

目的探讨海藻酸钠 /聚赖氨酸 (APA)微胶囊用于神经细胞 /组织移植的可行性。方法使用大功率高压脉冲微胶囊制备仪制备APA微胶囊 ,包埋分离自大鼠周围神经的神经细胞 /组织 ;应用ELISA双抗体夹心法检测微囊化神经细胞 /组织培养液中神经生长因子 (NGF)的浓度。结果包埋神经细胞 /组织的APA微胶囊在培养后及经过一定时间的空运后 ,囊内的神经细胞 /组织正常生存并保持分泌神经生长因子的功能。结论微囊化的神经细胞 /组织可以在体外培养和运输 ,并可分泌NGF。

ObjectiveTo investigate the feasibility of poly l lysne to preparation microencapsules for cell transplantation therapies.MethodsUsing drop generative technique preparation Alginate poly l lysne Alginate (APA) microencapsules containing nerve cell/tissue. The concentration of nerve growth factor in supernatant was detected by two antibody sandwich method of enzyme linked immunosorbent assay.ResultsThe nerve cell/tissue in microencapsules retain reliable cell viability and function. Conclusions The APA is proved with reliable biocompatibility and strength,would work as an immunoisolation tools to exert important function in nerve renovate.
