摘要
采用冷冻干燥法可以制得多孔丝素膜 ,其内部丝素的结构以无定形为主 ,含少量丝素Ⅱ ,平均孔径可在 10～3 0 0 μm范围内调节。这种多孔丝素膜具有良好的生物相容性 ,并可在多孔丝素膜中进行人表皮细胞的培养 ,毛细血管和成纤维细胞等能够长入其内而成活。
The porous fibroin membrane can be prepared by freeze drying, whose average pore diameter can be re gulated within the range of [HT5”SS]10 300[HT5SS]μm, in which the fibroin structure is mainly amorphous only with a little fibroin II Due to the good biocompatibility of this membrane, the cuticle cell of human can be cultivated in it ,also the capillary vessel and the fibroblast can grow in it.
