Furthermore, the outcomes on PI_v and PI_v+IKV confirmed the results found in the short-term adhesion analysis, resulting in a positive trend for cellular long-term attachment, differentiation and neurite sprouting for both the sequential surface modifications, thus leading to assume that vinyl groups and vinyl-bound IKV contribute to improve surface compliance for PC12 differentiation (Fig. 5C ).
