No significant difference was observed between the Luminal and HER2(+) breast cancer groups in terms of vimentin(+) and c-Kit(+) telocyte cell numbers; the number of CD10(+) (3.11 ± 0.128–2.54 ± 0.117; p = 0.003) and CD34(+) (2.85 ± 0.110–1.99 ± 0.083; p = 0.001) telocyte cells were significantly higher in the Luminal group than in the HER2(+) group (Figure 1 and Figure 2). This evidence concerns the gene ERBB2 and breast cancer.
