Fig. 2. Immunofluorescence for Sox2, neuronal and glial markers at
differentiation day 9. (A) Sox2 and β-tubulin in normal cells.
β-Tubulin-expressing cells show relatively high Sox2 positivity.
(B) Sox2 and MAP2. Top: normal; bottom: mutant. MAP2-positive cells
show significant Sox2 levels in both normal and mutant. (C) Sox2 and
GALC, marking oligodendrocytes. (D) Sox2 and GFAP.
