Alteration in cancer cell proliferation by AMTC and other cell lines. Jurkat and U937 cells were cultured alone or in the presence of different γ-irradiated cell types (AMTC or BM-MSC, dermal fibroblast cells, KG1a, U937 and Jurkat). Co-cultures were performed in both contact and transwell settings, at cancer cell: different cell types ratios of 1:2. After 1, 2 and 3 days of culture, Jurkat and U937 cell proliferation was assessed by [³H]-thymidine incorporation. Data are expressed as mean of more than four independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001 versus corresponding control sample.
