| 产品描述: | Tetrapeptide-21 is a bioactive peptide composed of four amino acids. Tetrapeptide-21 effectively enhances the vitality of human dermal fibroblasts. Tetrapeptide-21 upregulates the expression of key extracellular matrix (ECM) genes and promotes the synthesis of ECM proteins (such as type I collagen, hyaluronic acid synthase 1, and fibronectin). Tetrapeptide-21 has the efficacy of anti-wrinkle and improving skin elasticity, and has been reported to be used as a cosmetic ingredient. |
| 体外研究: |
Tetrapeptide-21 (0-72 h) 在后期 (48-72 h) 降低细胞活力,表现出潜在的细胞毒性,然而,协同注射富血小板纤维蛋白 (i-PRF) 可以逆转该肽的毒性作用,显著增强 FBH 细胞的细胞活力和增殖能力。 Tetrapeptide-21 (6-72 h) 在FBH 细胞可增加 COL1A1基因表达,与 i-RPF 联合使用时,还可上调 FN1 和 HAS1 的表达。 |
