We investigated the candidate genes which can become a marker to predict vascular endothelium growth factor (VEGF) secretional level of human mesenchymal stem cells (hMSCs)under ischemia. hMSCs were cultured under normal condition or ischemic condition. Cell supernatant was collected after 24hr and VEGF were measured with ELISA. We analyzed the correlation between gene expression before ischemia (Affymetrix HG-U133Plus2.0) and VEGF secretion after ischemia in hMSCs among six lots. 17 genes showed positive correlation in all combination of pre-ischemic gene expression and post-ischemic VEGF level (the change of amount or rate). Furthermore, RNAi against 2 of the 17 genes reduced VEGF secretion in response to ischemia. In this study, 17 genes were identified as candidate genes which could assess quality and efficacy of hMSCs after ischemia. In addition, it is suggested that 2 genes, the knockdown of which decrease the VEGF response, contribute to enhance VEGF secretion under ischemia.

我们研究了候选基因，这些基因可以成为预测缺血下人间质干细胞（HMSCS）的血管内皮生长因子（VEGF）分泌水平的标志物。 HMSC在正常状态或缺血状态下进行培养。 24小时后收集细胞上清液，并用ELISA测量VEGF。我们分析了缺血（Affymetrix HG-U133PLUS2.0）之前的基因表达与HMSC中缺血后的VEGF分泌之间的相关性。 17基因在缺血前基因表达和缺血后VEGF水平的所有组合（量或速率的变化）中显示出正相关。此外，针对17个基因中的2个对缺血的分泌减少了VEGF分泌。在这项研究中，将17个基因鉴定为候选基因，可以评估缺血后HMSC的质量和功效。此外，建议2个基因降低了VEGF反应，从而有助于增强缺血下的VEGF分泌。
