December 2023 in “Alzheimer's & dementia” In this rodent study, researchers found that the drug finasteride may reduce anxiety and depression-like behaviors in a model of aging, despite inducing metabolic disturbances and depressive-like behaviors in young rats, suggesting potential considerations for its use in elderly populations.
In this study, subcutaneous injection of mesenchymal stem cell-conditioned medium promoted regeneration of mice skin aged by D-galactose, improving skin thickness, vascularization, and collagen density.
March 2017 in “Zenodo (CERN European Organization for Nuclear Research)” This study found that probiotics, specifically the L. plantarum MTCC 1325 strain, may have protective effects against Alzheimer's-like symptoms induced by D-Galactose in animal models, suggesting potential therapeutic use for neurodegenerative disorders.

November 2022 in “Nutrients” In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.
This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.
