Abstract: Embodiments of the present disclosure pertain to isolated peptides of any one of SEQ ID NOS: 1-14, derivatives thereof, analogs thereof, homologs thereof, and combinations thereof. The isolated peptides may be in aggregated form, fibrillated form, in the form of three-dimensional hydrogels, or combinations thereof. Additional embodiments of the present disclosure pertain to methods of delivering the isolated peptides of the present disclosure into cells by exposing the cells to the isolated peptides and/or nucleotide sequences that express them. In some embodiments, the exposing results in the conversion of the cells to pluripotent stem cells. In some embodiments, the exposing occurs in vitro. In some embodiments, the exposing occurs in vivo in a subject by administering the isolated peptides and/or nucleotide sequences of the present disclosure to the subject.
