Figure 7From: Chromatin remodeling agent trichostatin A: a key-factor in the hepatic differentiation of human mesenchymal stem cells derived of adult bone marrowUrea production in sequentially TSA- and cocktail TSA-exposed hMSC. Gray area represents urea levels, produced by 4 hours-cultured adult hepatocytes. The graph is representative for 4 separate experiments, each performed in duplicate. **: Urea production significantly differs among sequentially TSA- and cocktail TSA-exposed hMSC with p < 0.01 (Student's t-test).Back to article page
