In terms of the chemotactic signals mediating MSC migration to ovarian cancer tissues, Coffelt et al. revealed the functional role of pro-tumorigenic peptide LL37, which is the C-terminal peptide of human cationic antimicrobial protein 18, in the recruitment of tumor-infiltrating MSCs to the metastatic tumor microenvironment [70]. The gene discussed is CAMP; the disease is neoplasm.
