Eguus asinus is one of the rare Chinese drugs famous for promoting blood circulation. In this experiment, it was employed to modify the silk fibroin (SF) by physical blending. Mouse embryonic fibroblasts NIH-3T3 were seeded on pure and modified SF surfaces. The morphological changes of cell on SF surfaces were characterized by optical microscope images. The cell adhesion diameter, the attachment force (F) of a single cell and cell proliferation on SF surfaces were measured by micropipette aspiration system and MTT assay. The results indicated that the fibroblasts seeded on modified SF had larger cell adhesion area, stronger initial attachment force and higher cell proliferation than did the pure SF. In conclusion, eguus asinus improved the adhesion and proliferation of fibroblasts on SF. The research promoted the further use of Chinese drug eguus asinus in tissue engineering.
