Abstract:Background The CD105+ cell clones isolated from renal cell carcinoma (RCC)were characterized as cancer stem cells. This study aimed to explore the antitumor mechanism of the transform growth factor-β(TGF-β) insensitive CD8+ T cells against CD105+ cells in vitro and vivo.
Methods The CD105+ cell clones were isolated from primary RCC cell lines and characterized by the immunofluorescence, qRT-PCR and western-blotting analysis. The expression levels of TGF-β1 were examined in 105 RCC tissues and correlation regr… Show more
