MKI67 and glioblastoma: Moreover, we could not observe any CW-induced pro-apoptotic/proliferative effect in DMSO treated organoids (Figures 9A-C), this suggests that the previously reported increase of CC3+ and Ki67+ cells at 72 hrs (Figures 7B, C) could be dependent only on an early response of GBM cells to the CW stimulation, which then extinguishes if cells are not re-exposed.
