초록

Fucoidan has been extensively studied as medicinal materials due to its biological activities including osteoblastic differentiation effect. However, osteoblastic effect by fucoidan is unknown in alveolar bone marrow derived mesenchymal stem cells (ABM-MSCs). The present study was undertaken to evaluate the effect of fucoidan on Osteoblastic differentiation in ABM-MSCs and explore its mechanism. Cell proliferation was analyzed by crystal violet staining. Osteoblast differentiation was determined by alkaline phosphatase activity, calcium accumulation assay and gene expression of osteoblast markers. We found that fucoidan induced cell proliferation of ABM-MSCs. Furthermore, fucoidan increased the ALP activity, calcium accumulation, and osteoblast specific genes such as Runx2, type I collagen alpha 1. Moreover, fucoidan induces the expression of asporin and bone morphogenic protein (BMP)-2 and asporin. Based on these results, these finding indicate that fucoidan induces osteoblast differentiation in ABM-MSCs and partially enhanced the mRNA expression of BMP-2 and asporin.
