Osteogenic differentiation after 28 and 42 days after staining with Alizarin-Red S. (a–c) Osteogenesis was observed in all samples ((a): 0 h; (b): 4°C; and (c): RT) on days 28 (i) and 42 (ii). The scale bar corresponds to 50 μm. (d) No significant differences between the groups were found on both examination dates (day 28: ; day 42: ; ).
