Abstract:
Objective To observe adhesion and growth of Sehwann cells(SCs) on small intestinal submueosa(SIS) and study the bioeompatibility of SIS with SCs.Methods The SCs of SD neonate rat were isolated and cultured in vitro,then were seeded on prepared SIS.At different times,the adhesion,growth and proliferation of SCs on SIS were observed by phase contrast microscope,histological examination,scanning e- lectron microscope and transmission electron microscope.Results By phase contrast microscope,SCs grew well on the edge of SIS after 3 and 5 days.SCs adhered tightly on the surface of SIS after 5 days through histo- logical examination.By scanning electron microscope,on the surface of SIS,SCs grew and adhered actively, prominence of cells body were obvious.They connected end-to-end with each other or arranged in clusters. Protein granules were secreted on cells surface.By transmission electron microscope,SCs grew in good condi- tion and adhered tightly on the surface of SIS.At the interface of SCs and SIS,prominence was seen to contact with SIS in the bottom of cell body.Conclusion SCs are able to adhere and grow well on the surface of SIS.As a scaffold,SIS has good biocompatibility with SCs.
