Self-assembling peptides (SAPs) are rapidly gaining interest as bioinspired scaffolds for cell culture and regenerative medicine applications. Bone Marrow Homing Peptide 1 (BMHP1) functional motif (PFSSTKT) was previously demonstrated to stimulate neural stem cell (NSC) viability and differentiation when linked to SAPs. We here describe a novel ensemble of SAPs, developed from the BMHP1 (BMHP1-SAPs), that spontaneously assemble into tabular fibers, twisted ribbons, tubes and hierarchical self-assembled sheets: organized structures in the nano- and microscale. Thirty-two sequences were designed and evaluated, including biotinylated and unbiotinylated sequences, as well as a hybrid peptide−peptoid sequence. Via X-ray diffraction (XRD), CD, and FTIR experiments we demonstrated that all of the BMHP1-SAPs share similarly organized secondary structures, that is, β-sheets and β-turns, despite their heterogeneous nanostructure morphology, scaffold stiffness, and effect over NSC differentiation and survival. Notably, we demonstrated the self-healing propensity of most of the tested BMHP1-SAPs, enlarging the set of potential applications of these novel SAPs. In in vitro cell culture experiments, we showed that some of these 10-mer peptides foster adhesion, differentiation, and proliferation of human NSCs. RGD-functionalized and hybrid peptide-peptoid self-assembling sequences also opened the door to BMHP1-SAP functionalization with further bioactive motifs, essential to tailor new scaffolds for specific applications. In in vivo experiments we verified a negligible reaction of the host nervous tissue to the injected and assembled BMHP1-SAP. This work will pave the way to the development of novel SAP sequences that may be useful for material science and regenerative medicine applications.
