生物活性

製品説明 Histamine, an organic nitrogenous compound, is involved in local immune responses regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. It is a potent H1 and H2 receptor agonist.
in vitro Histamine stimulates the proliferation of human articular chondrocytes in culture. Histamine is reported to modify the behaviour of many cell types in vitro, including chondrocytes, fibroblasts, macrophages, epithelial cells, endothelial cells, and T cells. Histamine also modulates the production of many cytokines and the expression of their receptors. Histamine regulates cellular processes through the expression of histamine receptors. Histamine stimulates the production of matrix metalloproteinases (MMPs)-13 and -3 (collagenase 3 and stromelysin-1, respectively) by histidine decarboxylase (HAC) in vitro[1].
in vivo Histamine has a recognised role in allergic and inflammatory reactions and is an important modulator of numerous physiological processes, including cell proliferation, angiogenesis, and vasopermeability[1]. Histamine dilates vasculature, increases blood flow, while it induces hyperpermeability in venula. It disrupts endothelial barrier formation of venula indicated by changes in vascular endothelial cadherin (VE-cadherin) localization at endothelial cell junction[3].

細胞アッセイ 細胞株 human articular chondrocytes
濃度 1-100 μmol/l
反応時間 6 days
実験の流れ Cells are grown to confluence in 80 cm2 culture flasks in Dulbecco's modified Eagle's medium (DMEM) + 10% fetal calf serum (FCS). At first or second passage, cells are seeded into 96 well culture plates, at densities of approximately 2×103 cells/well. After 24 hours the cells are treated with either DMEM +2% FCS alone (control), or DMEM + 2% FCS plus histamine range 1-100 μmol/l (minimum of eight wells for each treatment). The medium with or without histamine is replenished every 48 hours, and after six days cell growth is estimated.
