Furthermore, the apoptosis/proliferation cell rate was evaluated in xenograft (TUNEL/Ki67 staining) to rule out the possibility that decreased tumor growth by EGFP− cells is due to a less cell viability, The TUNEL and Ki67 staining results in the xenograft tissues by SiHa and C33A cells was shown in Fig 3G and summarized in Fig. 3H. Here, MKI67 is linked to neoplasm.
