Thus, apart from the mitogenic activity indicated by the mitosis genes already identified by PPP, BC lysates hold the ability to significantly drive chemokine expression in the gingival fibroblasts, indicated by CXCL6, CXCL5, CXCL8, CXCL1, and CXCL3, similar to what we have observed with PRF lysates and serum [30]. This evidence concerns the gene CXCL6 and breast cancer.
