keratinocyte migration

TB500 是一种胸腺素β4活性区域的合成分子。它可促进内皮细胞分化，角质形成细胞迁移，真皮组织中的血管生成，胶原沉积和减少炎症。

CAY10583是一种有效和选择性的BLT2 (leukotriene B4 receptor type 2)激动剂，增加TGF-β1和bFGF表达，促进角化细胞迁移和成纤维细胞增殖，加速糖尿病小鼠伤口愈合。

β-Defensin-2 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts.1It inhibits the growth of periodontopathogenic and cariogenic bacteria, includingP. gingivalisandS. salivarius.2β-Defensin-2 (30 μg/ml) stimulates gene expression and production of IL-6, IL-10, CXCL10, CCL2, MIP-3α, and RANTES by keratinocytes.3It also stimulates calcium mobilization, migration, and proliferation of keratinocytes when used at concentrations of 30, 10, and 40 μg/ml, respectively. β-Defensin-2 induces IL-31 production by human peripheral blood-derived mast cellsin vitrowhen used at a concentration of 10 μg/ml and by rat mast cellsin vivofollowing a 500 ng intradermal dose.4Expression of β-defensin-2 is increased in psoriatic skin and chronic wounds.5,6 1.Lehrer, R.I.Primate defensinsNat.
