Metastasis, which is a significant cause of mortality, is one of the most significant pathological processes of this cancer. Therefore, preventing the migration of cancer cells may be a useful therapeutic approach. The aim of this work was to investigate the impact of conditioned media and human Wharton&#39;s jelly stem cells (hWJSCs) on the migration and growth of the cervical cancer cell line Hela as well as the in vitro mRNA expression of genes involved in metastasis.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:150%"><span calibri="" style="font-family:"><b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><span style="color:black">&nbsp;Methods:</span></span></span></span></b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><span style="color:black"> After primary culture, cellular extract and conditioned medium of hWJSCs were prepared.

In addition, the cellular extract and conditioned medium of hWJSCs significantly decreased morphological alteration and migration of the cancer cells. The cellular extract and conditioned medium of hWJSCs modified the expression of <i>Vimentin</i> and <i>E-cadherin</i> genes to inhibit the cancer cell migration (p<0.05). However, the cellular extract indicated significantly profound inhibitory effects on the cervical cancer cells compared to the conditioned medium. </span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:150%"><span calibri="" style="font-family:"><b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><span style="color:black">Conclusions:</span></span></span></span></b><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><span style="color:black"> Our study demonstrated that the cellular extract and conditioned medium of hWJSCs inhibit the proliferation and migration of cervical cancer cells through the modification of migration-related gene expression.
