Fig. 6 From: BTB and CNC homology 1 (Bach1) induces lung cancer stem cell phenotypes by stimulating CD44 expressionInhibitors of MAPK signaling repressed CD44 + CSC characteristics. A Colony formation capacity. B A Transwell invasion assay was carried out to test cell invasion ability. C A tumor spheroid assay was performed to evaluate cell sphere formation ability. D Bach1, CD44, and p-p-38 protein expression in A549 CSCs. *P < 0.05Back to article page
