The first step involves supplementing a set of fibroblast cells (MG63) with osteoblast growth media for 7 days. With exposure to essential osteogenic (bone-formation) factors, these cells initiate the process of bone mineralization....
We track the level of calcium deposition in both sets of cell lines by introducing the Alizarin-red S stain. Alizarin reacts with the calcium cations and produces a bright red color....
