 Effects of mesenchymal stem cells (MSC) on in vitro proliferation and invasion of MHCC97‐H cells. (A) The OD value of the MHCC97‐H cells cultured with 50% MSC conditioned medium (MSC‐CM) was significantly increased as determined by CyQUANT assay. (B) Culture with MSC‐CM significantly decreased the number of migrating cells detected by Transwell assay. (C,D) Representative pictures of the Transwell assay observed under light microscope (×20), which indicated that migrating cells cultured with MSC‐CM (C) were significantly decreased compared with the controls (D). Error bar represents the standard error of the mean. *P < 0.05.
