Pomegranate fruit extract significantly enhances cartilage gene expression and chondrogenesis in human adipose-derived stem cells compared to Avocado/Soybean Unsaponifiable.
Human adipose-derived stem cells were first isolated, expanded in monolayer culture, and identified, and then seeded on fibrin scaffolds. These cell-impregnated scaffolds were divided into 4 groups: a control group, an Avocado/Soybean unsaponifiable (ASU) group, a Pomegranate Fruit extract (PFE) group, and a mixed ASU/PFE group. Each group was subjected to induction for two weeks with the corresponding substances, except the control group which only received chondrogenic medium.
The levels of cell viability, cartilage gene expression, matrix staining density, and collagen type II proteins in the PFE samples were found to be noticeably greater than other groups. Histological assessments further highlighted higher chondrogenic centers in the PFE group. This indicates that PFE significantly enhances chondrogenesis and cartilage gene expression in these cells, suggesting potential use in cartilage tissue engineering.
