Phosphorylation of Ser10 of p27Kip1 is involved in neurite outgrowth. (A) Cdk5+/+ NSCs were expanded in bFGF for 3 d and then transfected with Myc-tagged vectors bearing WT p27Kip1 (a–c), phospho-mimicking p27/10D (d–f) and nonphosphorylatable mutant the p27/10A (g–i). After removal of bFGF for 3 d to induce neuronal differentiation, cells were fixed and prepared for ICC, and immunoprobed with antibody to TuJ1 and Myc. Scale bar, 20 μm. (B) The histogram represents % of cells with well-developed neurites as opposed to cells with blunted neurites or no neurites, as obtained from four independent experiments.
