Establishment and Characterization of a Human Small Cell Osteosarcoma Cancer Stem Cell Line: A New Possible In Vitro Model for Discovering Small Cell Osteosarcoma Biology

Figure 18

Osteogenic differentiation on OSA3-CSCs and on OSA3-CSCs II lines_ALP. Osteogenic differentiation at 0 days (a-b), after 14 days (c-d), and after 21 days of induction by a cytochemical staining for the ALP with Fast Blue BB. In blue the ALP + cells and in red the nucleus counterstained by Propidium Iodide. Composite observation in brightfield and in fluorescence. Original magnifications: 20x. Bar size: 100 µm.
