(C) Abrogation of TNFα-mediated cancer stem cell population by Twist1 suppression.

(D) Representative photograph of metastatic lung nodules. 4T1-Luc cells with control and two shTwist1 stable clones were injected into BALB/c mice via the tail vein. The mice then received intraperitoneal injection of saline or 10 μg LPS. Seven days later, the mice were sacrificed and the entire lungs were stained with India ink and resected.
