目的:探讨一种提取高纯度和一定数量的嗅鞘细胞(OECs)的新方法,并研究其与神经支架修复材料PLGL的生物相容性.方法:从新生的 Wister 大鼠身上分离制备嗅鞘细胞并与PLGL共同培养.测量其接触角、吸附率、存活率等.结果:PDLLA的接触角(84.5°±1.5°)明显大于PLGL的接触角(52.6°±0.8°).PLGL的吸附率(80%)明显高于PDLLA(57%).PLGL的细胞存活率(88%)明显高于PDLLA(76%).结论:PLGL比PDLLA具有更好的亲水性、存活率以及良好的细胞生长状况.

Objective To investigate a new way to yield plenty of high purity olfactory ensheathing cells (OECs) and its biocompatibility with appropriate scaffolds.Methods OECs were prepared from neonatal Wister rats and co-cultured with poly [LA-co-(Glc-alt-Lys)] (PLGL). Its contact angle, adherent rate, and activity rate were tested.Results The contact angle of poly (D, L-lactic acid) (PDLLA)(84.5°±1.5°) was significantly higher than that of PLGL (52.6°±0.8°), the adherent rate of PLGL (80%) was significantly higher than that of the PDLLA (57%), and the activity rate of PLGL(88%) was much higher than that of the PDLLA (76%).Conclusion PLGL possesses better hydrophilicity and biocompatibility than PDLLA, and it can provide a better cell growth circumstance which is helpful for the effective treatment of nerve injury.
