Interleukin-6/interleukin-6 receptor complex promotes osteogenic differentiation of bone marrow-derived mesenchymal stem cells.

ABSTRACT:

Background

Interleukin-6 (IL-6) with IL-6 receptor (IL-6R) play an important role in the tissue regeneration in vivo, especially bone metabolism. Bone marrow -derived mesenchymal stem cells (BM-MSCs) are multipotent stromal cells, which are main origin of osteoblasts. However, the roles of IL-6 and IL-6R in the osteogenic differentiation of BM-MSCs are still unclear.

Methods

The expression of IL-6 and IL-6R was detected in BM-MSCs during osteogenic differentiation. The activation of the STAT3 pathway was assessed and its role in the osteogenic differentiation of BM-MSCs was determined using the specific inhibitor AG490. Exogenous IL-6/soluble IL-6R or antibodies against IL-6/IL-6R were used to confirm the mechanism by which the IL-6/IL-6R complex promotes the osteogenic diff
