Abstract (original English)
This study was designed to provide evidence of the neuroprotective of human adipose-derived mesenchymal stem cells (hADSCs) in oxygen-induced retinopathy (OIR). In vivo , hADSCs were intravitreally injected into OIR mice. Various assessments, including HE (histological evaluation), TUNEL (terminal deoxynucleotidyl transferase dUTP nick end labeling) staining, electroretinogram (ERG) analysis, and retinal flat-mount examination, were performed separately at postnatal days 15 (P15) and 17 (P17) to evaluate neurological damage and functional changes. Western blot analysis of ciliary neurotrophic factor (CNTF), glial cell line-derived neurotrophic factor (GDNF), and brain-derived neurotrophic factor (BDNF) was conducted at P17 to elucidate the neuroprotective mechanism. The P17 OIR group exhibited a significant increase in vascular endothelial cell nuclei and neovascularization that breached the ILM (inner limiting membrane) to the P17 control group. In addition, the retinal nonperfusion areas in the P17 OIR group and the number of apoptotic retinal cells in the P15 OIR group were significantly higher than in the corresponding hADSCs treatment group and control group. There was no significant thickness change in the inner nuclear layer (INL) but the outer nuclear layer (ONL) in the P17 OIR treatment group compared with the P17 OIR group. The cell density in the INL and ONL at P17 i
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
