Enhanced levels of Achaete-scute complex Homolog 1 (ASCL1) and Doublecortin (DCX) transcripts, markers of neural progenitors engaged in the early steps of neuronal differentiation [42], [43], were observed in human fetal neural stem cells and all glioma cell cultures examined as compared to adult cortical tissues (Figure 4B). This evidence concerns the gene DCX and central nervous system cancer.
