Intravenous administration of follistatin: Delivery to the liver and effect on liver regeneration after partial hepatectomy
K Kogure, Y Zhang, M Kanzaki, W Omata, T Mine, I Kojima – 1 August 1996 – When 1 μg 125I‐follistatin was administered into a rat intravenously, radioactivity levels in serum decreased rapidly. Analysis with a biexponential equation showed that the initial half‐ life and the terminal half‐life were 4.0 and 130.8 minutes, respectively. After 2 hours of infusion, approximately 9% of the follistatin infused remained in the liver, which was much more than that in kidney, spleen, pancreas, intestine, or lung.
