## Abstract The use of mesenchymal stem cells (MSCs) for cartilage repair has generated much interest owing to their multipotentiality. However, their significant presence in peripheral blood (PB) has been a matter of much debate. The objectives of this study are to isolate and characterize MSCs de

Abstract
The use of electromagnetic fields (EMFs) to treat nonunion fractures developed from observations in the mid‐1900s. Whether EMF directly regulates the bone marrow mesenchymal stem cells (MSCs), differentiating into osteoblasts or adipocytes, remains unknown. In the present study, we investigated the roles of sinusoidal EMF of 15 Hz, 1 mT in differentiation along these separate lineages using rat bone marrow MSCs. Our results showed that EMF promoted osteogenic differentiation of the stem cells and concurrently inhibited adipocyte formation. EMF increased alkaline phosphatase (ALP) activity and mineralized nodule formation, and stimulated osteoblast‐specific mRNA expression of RUNX2, ALP, BMP2, DLX5, and BSP. In contrast, EMF decreased adipogenesis and inhibited adipocyte‐specific mRNA expression of adipsin, AP‐2, and PPARγ2, and also inhibited protein expression of PPARγ2. These observations suggest that commitment of MSCs into osteogenic or adipogenic lineages is influenced by EMF. Bioelectromagnetics 31:277–285, 2010. © 2009 Wiley‐Liss, Inc.
