Effect of Increasing Doses of γ-Radiation on Bone Marrow Stromal Cells Grown on Smooth and Rough Titanium Surfaces

Figure 6

The effect of radiation on osteogenesis of BMSCs on PT and SLA surfaces. Calcium deposition almost covered the whole titanium disc on both PT and SLA surfaces under 0 and 2 Gy. At 8 Gy, the stained area was less than half. And the area was larger on SLA surfaces than on PT surfaces under the same dose of radiation. Red color indicated the positive areas.
