Fig 2. Cytometric assessment of CD133− and CD133+ and their cell cycle in control cells and after cultivation with 1mM VPA for 72 hrs in UKF-NB-3 and SH-SY5Y.

(A) VPA Increased the number of CD133+ cells in both cell lines. Blue—isotype control (IgG2b-PE); red—CD133 expression detected by 293C3-PE (CD133/2) antibodies. (B) CD133+ cells were mainly located in the S and G₂/M phases, while CD133− were mainly present in the G₀/G₁ phases.
