Effect of fetal calf serum and human serum enriched with ALE metabolites on the proliferation of human hepatocytes HepG2 cells, primary human subcutaneous pre-adipocytes and primary human articular chondrocytes: XTT activity. Human primary chondrocytes were incubated with serum from calf (A,C,E) or human origin (B,D,F) for 24 and 48 h. Primary human subcutaneous pre-adipocytes and HepG2 cells were incubated with serum from calf (C,E) or human (D,F) origin for 24 and 72 h. In each case, proliferation was measured using the XTT-based assay. Cells proliferate without any negative impact of human serum or metabolite enrichment (−absence; + presence). Groups with significant differences (p < 0.05) are indicated with different letters (a, b, c and d).
