Abstract (original English)

Background Kisspeptins (kp) activate a receptor coupled to a Gαq subunit (GPR54 or KiSS-1R) receptor to perform a variety of functions, including inhibition of cell motility, chemotaxis, and metastasis. In this study we have investigated whether kp-10, the most potent member of the kisspeptin family, can modulate CXCR4 (C-X-C chemokine receptor type 4) expression and mesenchymal stem cells (MSCs) migration that may influence the development of tumors. Materials and methods We compared the directional migration of MSCs treated with 10-100 or 500 nM kp-10 for 24 hours and no treated cells using an in vitro transmembrane migration assay. In addition, Chloromethylbenzamido Dialkylacarbocyanine (CM-Dil) labeled adipose-derived mesenchymal stem cells treated with 10-100 or 500 nM kp-10 and no treated cells were transfused via the tail vein to the melanoma tumor bearing C57BL/6 mice. After 24 hours, the mice were scarified, the tumors were dissected, and the tumor cell suspensions were analyzed by flow cytometry for detection of CM-Dil(+) MSCs. Results We have found that kp-10 increased the MSCs migration at 100 nM, while it decreased the MSCs migration at 500 nM, both in vitro and in vivo, with a significant increase of CXCR4 expression at 100 nM kp-10 compared to the no treated cells, but it had no significant difference between the various concentrations of kp-10. Conclusion Thus,
