Effect of hUCMSCs and hFFs on the proliferation ability of HTR-8/SVneo cells. (a) HTR-8/SVneo cells (2 × 10³ cells/well) were cultured in medium containing 0, 25, 50, or 100% hUCMSC or hFF supernatant in 96-well plates for 48 hours. (b) HTR-8/SVneo cells (10 × 10⁴ cells/well) were cocultured with hUCMSCs or hFFs at a concentration of 0, 2.5, 5, or 10 × 10⁴ cells/well in 6-well Transwell plates for 48 hours. ∗ represents significant differences versus control (P < 0.05); # represents significant differences between hUCMSCs and hFFs at an individual dose (P < 0.05).
