The Enhancing Effect of Dihydromorin, a Flavanonol Compound Isolated from Maclura Cochinchinensis (Kae-Lae), on the Proliferation and Differentiation of Umbilical Cord-Derived Mesenchymal Stem Cells into Osteoblasts.

Abstract

Mesenchymal stem cells isolated from umbilical cord tissue (UC-MSCs) are attractive candidates for cell-based therapy and regenerative medicine due to their remarkable self-renewal and differentiation ability. However, UC-MSCs obtained is limited. Therefore, searching for safe and effective agents in promoting the proliferation and differentiation of UC-MSCs is an alternative strategy to improve the efficacy of MSC-based therapy in degenerative disorders. Phytochemicals isolated from medicinal plants, such as polyphenols, flavonoids, and other plant-derived chemicals have been reported to exhibit proliferative and anti-senescent effects in MSCs. This study aims to evaluate the effects of dihydromorin, a flavanonol compound from Maclura Cochinensis or Thai herbs as "Kae-Lae", a medicinal plant found in Thailand on the proliferation and osteogenic differentiation of UC-MSCs. Firstly, MSCs were isolated from leftover umbilical cord tissue and characterized for their morphology, immunophenotype, and multi-lineage potentials. UC-MSCs were treated with different concentrations of dihydromorin. The results demonstrated that dihydromorin at 1-10 µM increased the proliferation of UC-MSCs as determined by the MTT assay and the growth curve analysis. Interestingly, dihydromorin accelerated the osteogenic differentiation of UC-MSCs as indicated by the increased alkaline phosphatase (ALP) and calcium deposition as determined by ALP staining and Alizarin Red S staining, respectively. Dihydromorin also enhanced osteogenic markers genes, including RUNX2, OSX, ALP, OCN, and COL1A1. The osteogenic effect of dihydromorin tended to be mediated through the activation of the Wnt/β-catenin signaling pathway as active-β-catenin is increased by dihydromorin which can be translocated into the nucleus and activate the expression of genes involved in cell proliferation and osteogenic differentiation of UC-MSCs. This study demonstrates the osteogenic potential of dihydromorin in human UC-MSCs, providing a foundation for future investigations into its possible applications in bone regeneration and therapeutic strategies.
