Figure 4. Correlation of immunoexpression of CSC-representative markers with Ki67.

Figure 4

Comparative analysis using linear regression test of CSC-representative markers (Nanog, OCT-4, and CD133) with Ki67 showed that only OCT-4 was found positively correlated with Ki67. However, there were no correlations at all between the expressions of Nanog and CD133 and Ki67.
