Figure 1From: Therapy with un-engineered naïve rat umbilical cord matrix stem cells markedly inhibits growth of murine lung adenocarcinoma Direct co-culture of a small number of rat UCMSCs significantly attenuated the growth of LLC cells. Rat UCMSCs (300, 500 and 1000 cells/well) were co-cultured with 3 × 103 LLC (rat UCMSCs: LLC ratio, 1:10, 1:6 and 1:3). After three days of co-culture, the MTT assay was carried out. Panel A shows the morphology of LLC alone or LLC co-cultured with rat UCMSCs for 72 hrs. Scale bars in the pictures indicate 1000 μm. Panel B shows the summarized results from the MTT assay. The experiment was performed twice with 6 determinations at each point.Back to article page
