Abstract

The initial attachment of mesenchymal stem cells (MSCs) to substrates and osteogenic differentiation are supported by culture on a hydroxyapatite substrate. Cell attachment areas of rat MSCs after 2. h of culture on hydroxyapatite substrates with various microstructures and the osteogenic differentiation activity thereafter were measured. The perceived outcome was that, after 2. h of culture, rat MSCs with a small attachment area would have a high osteogenic differentiation activity, whereas those with a large attachment area would have a low osteogenic differentiation activity. Furthermore, rat MSCs with a small attachment area had many cytoplasmic processes, while those with a large attachment area revealed clear stress fibers and focal contacts. These results suggest that cell attachment area of rat MSCs after 2. h of culture has a strong effect on the osteogenic differentiation of rat MSCs. Thus, the measurement of cell attachment area after 2. h of culture could become valuable for estimating the osteogenic differentiation activity of rat MSCs thereafter.
