Abstract

Due to the therapeutic characteristics of bone marrow (BM)‑derived mesenchymal stem cells (MSCs), clinical trials are testing the use of autologous or allogeneic MSCs for the treatment of several conditions. These therapies require large numbers of MSCs and numerous studies are attempting to find substances that could enhance the egression of endogenous MSCs from the BM into the periphery and increase their proliferation in vivo and in vitro. It has been reported that substance P (SP) has the potential to increase the expansion of MSCs in vivo and to induce their mobilization from the BM into the periphery. The aim of the present study was to investigate the effects of SP on the migration and proliferation potential of two BM‑derived MSC‑like cell lines, ST2 and OP9. SP was found to induce the migration potential of ST2 cells in vitro. Furthermore, SP increased the proliferation of the MSCs cell line, OP9 cell line. Cyclin D1 expression was observed to increase in the OP9 cells, indicating the activation of the cell cycle in response to SP. The upstream signals involved in these phenomena have yet to be elucidated, although previous studies have proposed the activation of the extracellular signal‑regulated kinase‑1/2 and Wingless/β‑catenin pathways as possible mediators of the cellular proliferation of human MSCs in response to SP. The present results therefore suggest that SP would facilitate the obtainment of higher numbers of endogenous MSCs from patients or donors and/or shorten the process of in vitro expansion that could cause the MSCs to undergo changes in their innate therapeutic characteristics prior to their use in therapy.
