The Effect of Sodium Valproate on the Glioblastoma U87 Cell Line Tumor Development on the Chicken Embryo Chorioallantoic Membrane and on EZH2 and p53 Expression

Figure 3

Frequency of U87 cell tumor groups with invasion into the CAM mesenchyme and localized only on the CAM. The investigated groups were U87 cell tumors nontreated with NaVP (n = 10), treated with 4 mM of NaVP (n = 10), and treated with 8 mM of NaVP (n = 10). Tumors invading the CAM mesenchyme are presented as the common group containing tumors of which part of tumor invaded the mesenchyme and those localized only in the mesenchyme.
