Abstract
A novel protein delivery system to generate induced pluripotent stem (iPS) cells is described. The delivery system comprises a construct with a receptor binding domain that recognizes a receptor in a somatic cell, a translocation domain that allows the transfer of an inducer into the cytosolic space, and a cargo bearing domain to which the inducer is attached and facilitates transfer of the inducer into the cell.
