Analysis of alkaline phosphatase (AP) activity. Bright-field images obtained at 100× (a) or 32× (b) magnification, showing some red-stained cell groups after action of alkaline phosphatase on Fast Red in presence of Napthol AS-mx phosphate. Bars = 70 μm (top panels) and 150 μm (bottom panels). AA-MSC abdominal adipose tissue mesenchymal stem/stromal cell, DS-MSC dermal skin tissue mesenchymal stem/stromal cell, PB-MSC peripheral blood mesenchymal stem/stromal cell, SCA-MSC subcutaneous adipose tissue mesenchymal stem/stromal cell
