Different gene mRNA expression in p75
NTR+ and p75
NTR- subpopulation. mRNA expression level was measured by real-time qPCR. p63 (A) and Bmi-1 (B) were more intensely expressed in p75NTR+ cells compared with p75NTR- cells. Conversely, CTR1 (C), involucrin (D), cytokeratin 13 (E), β1-integrin (F) and β4-integrin (G) expression were lower.
