Behavior Of Retinal Pigment Epithelial Cells Cultured On Silk Films
POLYMER-KOREA(2014)
Abstract
The retinal pigment epithelium (RPE) plays an important role in maintaining a healthy retina and the degeneration of RPE caused a number of retinal diseases. The transplantation of RPE has recently become a possible therapeutic modality for retinal degeneration. To transplant RPE cells securely, substrates are essential, and then as a substrate, we fabricated films using silk that has unique mechanical properties and biocompatibility. After the FTIR spectra, contact angle and biodegradation of silk films were confirmed, RPE cells were seeded and the influence of RPE cells on silk films was examined. We measured the cell adhesion, cell viability, morphology and specific mRNA expression by MIT assay, SEM, immunofluorescence and RT-PCR. In this study, we confirmed that attachment, proliferation and phenotype maintenance of RPE cells cultured on silk films were great, and thereby we were able to confirm the potential applications of silk films as tissue engineering carrier for regeneration of retina.
