Figure 4. LPS-induced tumor-cell adhesion is Kupffer cell (KC)-dependent. (A) Tumor cells in the livers of control or KC-depleted rats that were treated with LPS. Red: DiI-labeled CC531s, blue: cell nuclei, arrow heads point to CC531s cells. (B) Quantification of tumor cells in the livers of control or KC-depleted rats that were treated with LPS. n = 4 per group; ***p < 0.001 (C) ZO-1 staining in the livers of control or KC-depleted rats that were treated with LPS. Green: ZO-1, blue: cell nuclei.
