简介内容:TP508 TFA, a 23-amino acid segment of the thrombin molecule´s receptor-binding domain, is a nonproteolytic thrombin peptide. It activates endothelial NO synthase (eNOS) to enhance nitric oxide (NO) production in human endothelial cells, thereby stimulating both endothelial cells and stem cells for tissue revascularization and regeneration [1] [2].
