  1. Differentiated Adipocytes, Preadipocytes or Adipose Tissue cultures were incubated for 24 h in the presence of thrombin (10 U/ml). Cytokine and growth factor release to the medium is in pg/ml for adipocytes and preadipocyte cultures and pg/ml/g for adipose tissue cultures. % induction is the average of the individual % cytokine/growth factor induction from each sample. The values are shown as the mean ± SEM. aP < 0.05 thrombin vs. control.
