The qPCR results also showed that the expression levels of osteoblast-related genes (BMB2, BSP, OPN, and RUNX2) were significantly higher in SK-PDLSCs cultured in OM than in SK-N-SH cells cultured in CM or OM or in SK-PDLSCs cultured in CM (Figure 2C). This evidence concerns the gene RUNX2 and ocular melanoma.
