Immortalizing Mesenchymal Stromal Cells from Aged Donors While Keeping Their Essential Features

Figure 8

Alizarin Red staining of iMSC#8 (a), iMSC#9 (b), and 143B osteosarcoma cell line (c) after 21 days of osteogenic induction. Percentage of Alizarin Red-stained area for each sample is shown (scale bar: 100 μm; magnification: 10x). Osteogenesis-related gene expression after culturing in basal medium (BM) and osteogenic medium (OM) is shown for iMSC#6 (d), iMSC#8 (e), and iMSC#9 (f) ( value > 0.05).
