Mesenchymal stem cell-like cells from children foreskin inhibit the growth of SGC-7901 gastric cancer cells
چکیده انگلیسی

Mesenchymal stem cells (MSCs) become a research hotspot in recent years because of their roles in regenerative medicine and tissue injury repair. However, the limited source for MSCs hampers its clinical application. In this study, we isolated and identified human mesenchymal stem cell-like cells from foreskin (hFMSCs) by explant culture. HFMSCs had similar morphology and immunophenotype to that of human bone marrow derived-mesenchymal stem cells. HFMSCs formed colonies after 9 days of inoculation and could be propagated for more than 50 passages. HFMSCs had a normal karyotype and high G0/G1 phase independent of passage number. Further, hFMSCs could be induced to differentiate into osteocytes and adipocytes. We found that the growth of SGC-7901 (human gastric adenocarcinoma) cells could be suppressed by simultaneous injection of hFMSCs in vivo. HFMSCs also inhibited SGC-7901 cell proliferation in vitro. HFMSC co-injection resulted in a decrease in PCNA-positive and an increase in apoptotic tumor cells. HFMSCs derived conditioned medium inhibited the expression of BCL-2 while increased the expression of BAX and caspase-3 in SGC-7901 cells. Taken together, our findings suggest that children foreskin is a new source for MSCs and hFMSCs could inhibit gastric cancer cell growth both in vitro and in vivo.
