摘要(Abstract):
目的 :探讨几丁糖作为组织工程技术中软骨细胞培养支架的可行性。方法 :采用几丁糖无纺网作为细胞培养支架 ,使用前首先用 10 %多聚赖氨酸包埋以增加其对软骨细胞的吸附性 ,然后把几丁糖支架与软骨细胞一起进行体外培养 ,在倒置显微镜下观察几丁糖对软骨细胞生长的影响。结果 :包埋后的几丁糖支架与软骨细胞一起体外培养10d ,软骨细胞数目增加约 6倍 ,并且与几丁糖支架牢固结合不易丢失。结论 :几丁糖无纺网经 10 %多聚赖氨酸包埋后 ,对软骨细胞吸附性增强 ,并且几丁糖具有良好的生物学特性 ,因此几丁糖符合组织工程对细胞培养支架的要求 ,有可能成为组织工程中一种良好的细胞培养支架
