EPCAM and neoplasm: Since previous study showed that exogenous TSLP treatment induced anti-apoptotic BCL2 expression by murine intestinal epithelial cell line mICcl2, indicating a possible anti-apoptotic effect of TSLP [23], we next sorted EpCAM+ cells from tumor-surrounding tissues to examine the effect of TSLP on non-transformed human colonic epithelial cells.
