Effects of FGF-2 and antioxidants on ADMSCs proliferation under normoxic or hypoxic conditions. (A) Cell density in the presence (ImF) or absence (Im) of FGF-2. (B) Cell density in the presence of FGF-2 (ImF), FGF-2 with antioxidants (ImF-A), or FGF-2 under hypoxic conditions (ImF-H). (C) Relative telomere length of ADMSCs after 14 days under the four culture conditions as assessed by quantitative PCR. Medium was changed every 3 days, starting on the third day. Each bar represents the mean value ± SD (n = 3). * P < 0.05. ** P < 0.01. *** P < 0.005.
