Bar chart representing the results of a CCK-8 assay to quantify hMSC proliferation on Ti5 and control microspheres in ultra-low attachment cell culture plates at time points of 1, 4, and 7 days when DMEM and a commercially available mesenchymal stem cell growth medium DXF (Promocell GmbH, Germany) are used as the culture medium. The control comprises silica glass microspheres (Polysciences Inc.). Error bars represent ±SD and n = 2. ** and *** indicate p < 0.01 and p < 0.001, respectively.
