제목 A Study of Proliferation and Morphology of Retinal Pigment Epithelial Cell on SIS/PLGA Film
초록 Porcine small intestine submucosa(SIS) is accellular tissue and widely used as a biomaterials without immunorejection responses. Poly(lactic-co-glycolic acid)(PLGA) is a biodegradable synthetic polymer with acceptable mechanical strength and well-controlled degradation rate. RPEs were isolated from retina of rabbit. We fabricated SIS/PLGA films using 20 wt% of SIS. We measured MTT to confirm cellular of cell number attached on film at 1, 3, 7, and 14 days. Morphology of cellular adhesion on films was confirmed by scanning electron microscope (SEM) at 1, 3, and 7 days. RT-PCR was conducted to confirm mRNA expression of RPE65 as RPEs marker and expression of cytokeratin, RPE65 were determined by Immunofluorescence staining. These results suggest that SIS provides suitable surface to RPEs. This research was supported by WCU (R31-20029) and SCRC (SC4100).
