Demonstrates the protective effects of a novel hydrogel on vitrified-thawed ovaries, suggesting enhanced fertility preservation methods for female cancer patients.
Key Points
The study aims to evaluate the protective effects of a hydrogel loaded with CM-UCMSCs on vitrified-thawed ovarian tissue during in vitro culture.
Development of an antioxidant-enriched hydrogel (PG-gel) using N-acetylcysteine-modified gelatin.
Loading the hydrogel with conditioned medium from umbilical cord mesenchymal stem cells (CM-UCMSCs).
In vitro culture of vitrified-thawed ovarian tissue with various treatment groups.
Assessment of oxidative stress, apoptosis, and follicle morphology and function.
Significant suppression of intracellular reactive oxygen species generation in the PG + CM-UCMSCs group.
Markedly reduced follicle loss and improved follicle morphology.
Decreased collagen deposition and lower apoptosis rates compared to other culture groups.
Enhanced mitochondrial metabolism with changes in gene expression related to apoptosis and energy metabolism.
