Dexamethasone has been used: · in culture media to induce differentiation of adipose-derived stem cells into osteogenic tissue · as a component of adipocyte differentiation medium · for in vitro stimulation of primary normal human bronchial epithelial cells (NHBE) and airway smooth muscle (ASM) |
| 产品介绍 | Dexamethasone is a potent synthetic member of the glucocorticoid class of steroid drugs, and an interleukin receptor modulator that has anti-inflammatory and immunosuppressant effects. |
| 生化机理 | Dexamethasone is an antiinflammatory glucocorticoid that induces the production of phospholipase A2 inhibitory protein (lipocortin). It also inhibits induction of nitric oxide synthase (IC50=5 nM). Dexamethasone has been shown to cause reduction in cyclin A and Cdk2 activity, inhibition of G1/S transition in osteoblasts and inhibition of phosphorylation of Rb protein. Dexamethasone has been observed to induce apoptosis in human thymocytes and eosinophils, but inhibits apoptosis in neutrophils. Dexamethasone is an activator of IDO. |
