Figure 4

Alkaline phosphatase (ALP) expression in DBSCs. (a) ALP expression assayed by ALP cytochemical assay (purple staining) in DBSCs cultured in osteogenic conditions and treated with irisin or not (Ctr) for 7 days. Representative phase contrast pictures were chosen for the figure. Scale bar: 100 μm. (b) The graph shows the quantification of ALP % area presented as box-and-whisker plots with median and interquartile ranges, from max to min, and is representative for five independent experiments performed in quadruplicates.
