Real-time-guided bone regeneration around standardized critical size calvarial defects using bone marrow-derived mesenchymal stem cells and collagen membrane with and without using tricalcium phosphate: an in vivo micro-computed tomographic and histologic experiment in rats
The use of stem cells to accelerate bone regeneration has been monitored in real time in rats using three-dimensional imaging. The work was carried out by Khalid Al-Hezaimi and colleagues at King Saud University, Saudi Arabia, in collaboration with No-Hee Park of the University of California. Mesenchymal stem cells were harvested from rat hind leg bones. The researchers then drilled holes in rat skulls and filled them with stem cells covered with collagen membrane with and without tricalcium phosphate granules, or collagen membrane alone. Micro-computed tomography revealed that differentiation of stem cells into mature bone cells took approximately 2 weeks. Bone regeneration over a 10-week period was significantly faster with the stem cell treatments. Adding tricalcium phosphate weakened the regenerated bone, despite previous work suggesting it might promote bone cell formation
