Effect of I2 on tumor growth in NOD/SCID mice. HeLa cervospheres were pre-incubated with 200 μM I2 or deionized water for 24 h. Each animal was inoculated with both subpopulations on each side (n = 6) and circles indicate sites of xenografts (a). Table showing the number of tumors developed in vivo (b). Average growth of tumor volume of xenograft tumors through the days (c). Average tumor volume size of cervospheres treated and untreated with I2 (d). Data are expressed as mean ± SD (n = 6 independent assays), and the asterisk indicates a significant difference with respect to the control (**P < 0.01) (d)
