Thus, changing the chemical composition of the BC influenced the DSPP and BSP expression in the hDPSCs.Fig. 2indicates that the BC groups showed the highest level of DSPP expression at a concentration of 1:5 (BC 3) at an observation time of 7 days, while they showed the lowest at a concentration of 1:1 (BC 1) at an observation time of 7 days. Here, DSPP is linked to breast cancer.
