Improvement of osteogenic differentiation potential of placenta-derived mesenchymal stem cells by metformin via AMPK pathway activation.

Background: Placenta-derived human mesenchymal stem cells (PL-MSCs) have gained a lot of attention in the field of regenerative medicine due to their availability and bone-forming capacity. However, the osteogenic differentiation capacity of these cells remains inconsistent and could be improved to achieve greater efficiency. Although metformin, a widely used oral hypoglycemic agent, has been shown to increase bone formation in various cell types, its effect on osteogenic differentiation of PL-MSCs has not yet been investigated.

Effect of the polyphenol flavonoids fisetin and quercetin on the adipogenic differentiation of human mesenchymal stromal cells.

Fisetin and quercetin, polyphenol flavonoids, have been shown to have a wide range of beneficial pharmacological effects including anti-inflammatory, antioxidative, and anti-cancer. Our previous work shows that fisetin also affects the specification of the adipogenic-osteogenic lineage of human mesenchymal stem cells (hMSCs) by modulating the Hippo-YAP signaling pathway. Although quercetin has a structure similar to that of fisetin, its effects on the functional properties of hMSCs have not yet been investigated.
