(a) Pictures and quantification of NS AB-ECFCs and S AB-ECFCs stained using the SA-β-gal assay (n = 13). Analysis of GDF15 expression and secretion by NS AB-ECFCs and S AB-ECFCs by (b) RTqPCR (n = 13), (c) western-blot (n = 11) and (d) ELISA (n = 8). (e) GDF15 effects on cellular senescence from passages 3 to 6 (n = 3). Data are presented as the mean ± SEM. ns = non-significant, ** P <0.01 and *** P <0.001 compared to NS AB-ECFCs.
