Mesenchymal stem cells derived osteoblasts or mesenchymal stem cells osteogenic differentiation could represent an important way to increase the healing after dental implantation. Aim: This research investigated the effects of various environmental stimuli (in vitro) on the osteogenic differentiation of MSCs and the subsequent development of calcium deposits by these cells. Materials and methods: Calcium phosphate deposition was quantified using the Alizarin red method via spectrophotometry. Results: The calcium deposited solely by mesenchymal stem cells derived osteoblasts was considered to be 100% all the time. When 1% platelet-rich plasma was added in the culture medium, the calcium deposits increased by 20% (on average). Different amounts of calcium deposits were developed by MSCs-derived osteoblasts when platelet-rich plasma was administered concurrently with: rosavin, rapamycin, metformin, “young” exosomes, “adult” exosomes, lower power CO2 laser, extracellular shock waves, and PI3K/HDAC11 inhibitor. Conversely, platelet-poor plasma did not significantly modify the calcium deposits realized by MSCs-derived osteoblasts. Conclusions: All the obtained data suggest that calcium deposits resulting from the functioning of mesenchymal stem cells-derived osteoblasts could be significantly and especially increased by cellular mechanisms related to “young” exosomes, rosavin, acetylation, rapamycin, “adult” exosomes and metformin.
