ECCM increases the clonogenic potential and CD133 expression of CD133⁻ GBM cells. a Indicated is the clonogenic potential of the CD133⁻ fraction of G073 (left) and G062 (right) cultures in control medium or ECCM and of CD133⁺ cells in control medium, scored 2 weeks after sorting (n ≥ 3). b, c G073 (b) and G062 (c) CD133⁻ cells were plated in control medium or ECCM directly after sorting. Quantification and FACS profiles depict CD133 expression 24 h (G073) or 72 h (G062) after sorting (n = 3)
