Both α-syn, nestin, and CD133, which are negligibly expressed within astrocytes in baseline conditions are abundant within U87MG, GBM cell line and they do pass from the latter to the former in the trans-well system (Figure 7, Figure 8, Figure 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16, Figure 17, Figure 18, and Supplementary Figures S5–S8). The gene discussed is PROM1; the disease is glioblastoma.
