Abstract:
:Retinopathy has become one of the major factors that lead to blindness worldwide. Although many clinical therapies are concerned about such disease, most of them focus on symptoms alleviation. In this study, we aim to investigate whether coculture retinal stem cells (RSCs) with bone marrow mesenchymal stem cells transfected with angiogenin-1 (Ang-1-BMSCs) affects the damaged retinal tissue of oxygen-induced retinopathy of prematurity (OIR-ROP) mice. After OIR-ROP mouse model establishment, Ang-1-BMSCs, RSCs, and OIR-ROP retinal tissues were cocultured in a a transwell chamber. RSCs proliferation and the expression of Ang-1, insulin-like growth factor-1 (IGF-1) in the supernatant of RSCs, as well as β-tubulin and protein kinase C (PKC) expression were evaluated. Finally, the repair of OIR-ROP mice retinal tissues was observed by injecting Ang-1-BMSCs + RSCs. In the OIR-ROP mouse model, RSCs cocultured with OIR-ROP retinal tissues could be induced to differentiate into cells expressing β-tubulin and PKC and promote the expression of Ang-1 and IGF-1. coculture of Ang-1-BMSCs further enhanced the proliferation and differentiation of RSCs by promoting the expression of Ang-1 and IGF-1. Coculture of RSCs + Ang-1-BMSCs induced differentiation of Ang-1-BMSCs through interaction among intercellular factors and restored the damaged retinal tissue of OIR-ROP mice. Collectively, our study provided evidence that coculture of Ang-1-BMSCs and RSCs could promote the proliferation and differentiation of RSCs and improve the treatment for the damaged retina tissue of OIR-ROP mice.
