Figure 1. Sorting and identification of stem cells from cell line SCC-9.
(A-B), CD44+ cells sorted by flow cytometry; (C), relative expression of miR-433 and FAK mRNA in the stem cells and non-stem cells; (D), cell cycle detected by flow cytometry; (E), specific protein expressions of stem cells detected by immunofluorescence staining; *, P < 0.05, compared with non-stem cells; SCC, squamous cell carcinoma; miR-433, microRNA-433; FAK, focal adhesion kinase.
