磷酸盐缓冲液(PBS)通常在实验室中被作为稀释液、冲洗细胞悬浮液以及用于清洗培养瓶和培养皿,也常作为细胞培养基的添加物。这项研究评估了含有不同浓度的钙离子和镁离子的PBS溶液基质对人外周血液单个核细胞(PB-MCs)趋化因子释放的影响。当PBMCs暴露于含量增加的+/+PBS中时,发现白介素-8也会相应增加。因为细胞外钙离子浓度对细胞迁移有一定影响,趋化因子的分泌表明细胞培养过程中增加钙离子浓度是另一种很重要的调节机理。
燐痠鹽緩遲液(PBS)通常在實驗室中被作為稀釋液、遲洗細胞懸浮液以及用于清洗培養瓶和培養皿,也常作為細胞培養基的添加物。這項研究評估瞭含有不同濃度的鈣離子和鎂離子的PBS溶液基質對人外週血液單箇覈細胞(PB-MCs)趨化因子釋放的影響。噹PBMCs暴露于含量增加的+/+PBS中時,髮現白介素-8也會相應增加。因為細胞外鈣離子濃度對細胞遷移有一定影響,趨化因子的分泌錶明細胞培養過程中增加鈣離子濃度是另一種很重要的調節機理。

Phosphate-buffered saline (PBS) solutions are commonly used in laboratories for dilutions, washing cell suspensions, rinsing, as well as an additive to cell culture media. The present study evaluated chemokine secretion of peripheral blood mononuclear cells (PBMCs) incubated in medium containing PBS solutions with varied concentrations of calcium and magnesium. A dose-dependent increase of interleukin-8 (IL-8) was found when PBMCs were exposed to increasing concentrations of +/+ PBS. Since extracellular calcium gradients have been attributed to induce cellular migration, the secretion of chemokines suggests an important additional modulatory mechanism of heightened calcium levels in cell culture conditions.
