*2.4. Preparation of Micellar Copolymer Solutions Containing rAAV-FLAG-hsox9 Vectors*

Copolymer solutions (PF68 or T908) were prepared in 10% sucrose aqueous solution at 4 ◦C, mixed with rAAV-FLAG-h*sox9*, and maintained in ice-water bath for 30 min prior to their use as previously described [21–23]. The final micellar concentration into the culture medium was 2%. Effective interaction between the vectors and the polymeric micelles was confirmed by dynamic light scattering and electron microscopy [21–23].
