Figure 1. Effect of Sfrp5 on adipokine and myokine release (unstimulated conditions).

Primary human adipocytes (A–C) and primary human skeletal muscle cells (D–E) were exposed to increasing amounts of Sfrp5 for 24 h. Cytokine release by the adipocytes and myotubes was quantified by ELISA, and expressed as mean ± standard error of the mean (A–C: n = 5; D–E: n = 4).
