摘要

Our results indicate that SEMA3C and SEMA4D inhibit osteogenic differentiation of hMSCs, demonstrated by lower production of most osteoblast differentiation markers. Both SEMA4D and SEMA3C increased DNA and decreased alkaline phosphatase activity compared to control groups, suggesting the cells are retained in a proliferative state. Importantly, neither factor abrogated the influence of the surface, indicating a balance between surface activation and inhibition by Sema4D and 3C. Sema3C is an important molecule in the regulation of osseointegration process.
