Effects of indirect co-culture of DPSCs and CRC cells on the invasive ability of CRC cells. A. Image of migrated cells stained with crystal violet underside of the inserts. Magnification, 4× and 10×. B. Percent of metastatic cancer cells was normalized to the crystal violet absorbance unit at 570 nm and compared with the control. Data represented no significant differences in invasion of cancer cells between the control group and the co-culture group and are expressed as mean ± SD in triplicate

DPSC-CM: Dental pulp stem cell-conditioned medium; CRC: Colorectal cancer
