Abstract
Small molecule-based bone tissue engineering is emerging as a promising strategy for bone defects restoration. In this study, we intended to identify the roles and mechanisms of AR-A014418, a highly selective inhibitor of GSK3, on the osteogenic differentiation. We found that AR-A014418 exhibited a dose-dependent effect on osteogenic differentiation of human adipose-derived stem cells (hASCs). hASCs treated with AR-A014418 showed higher activity of ERK and mTORC2/Akt signaling. Administration of ERK inhibitor U0126 or knockdown of RICTOR by siRNA attenuated AR-A014418 induced osteogenic differentiation of hASCs. Our results suggested that AR-A014418 significantly promoted osteogenic potential of hASCs partially by the activation of ERK and mTORC2/Akt signaling pathway, and might be used for bone tissue engineering as an osteo-inductive factor.
