Effects of Laser Application on Alveolar Bone Mesenchymal Stem Cells and Osteoblasts: An In Vitro Study. | LitMetric
Unlabelled : Mesenchymal stem cells isolated from the bone marrow have a great differentiation potential, being able to produce many cell lines, including osteoblasts. Osteoblasts have an important role in bone remodeling by actively participating in the maturation and mineralization of the extracellular matrix. The aim of this study was to determine the effect of laser application on the viability and proliferation of osteoblasts.Methods : Alveolar bone was harvested from 8 patients and placed into a culture medium to induce proliferation of mesenchymal stem cells. These were differentiated into osteoblasts in special conditions. The cells from each patient were split into two groups, one was treated using a 980 nm laser (1W output power, pulsed mode, 20 s, 50 mm distance) (laser "+") and the other one did not receive laser stimulation (laser "-").Results : Using the confocal microscope, we determined that the cells from the laser "+" group were more active when compared to the laser "-" group. The number of cells in the laser "+" group was significantly greater compared to the laser "-" group as the ImageJ-NIH software showed ( = 0.0072).Conclusions : Laser application increases the proliferation rate of osteoblasts and intensifies their cellular activity.
