Larger tumor was formed in nude mice transplanted with mixed CTPE-induced BEAS-2B cells at passage 30 and THP-1 cells.

<p>(<b>A</b>) Representative examples of tumor formation in nude mice on the 30^th day after injection (n = 6/group). (<b>a</b>) untrested BEAS-2B cells, (<b>b</b>) BEAS-2B cells induced with DMSO, (<b>c, d</b>) CTPE-induced BEAS-2B cells at passage 20 and 30, (<b>e</b>) CTPE-induced BEAS-2B cells at passage 30 mixed with THP-1 cells. Red arrow showed tumors. (<b>B</b>) Representatives of tumor removed from nude mice after 30 days transplantion. (<b>a–b</b>) CTPE-induced BEAS-2B cells at passage 30, (<b>c-d</b>) CTPE-induced BEAS-2B cells at passage 30 mixed with THP-1 cells.
