Abstract

This invention provides a method of using a porcine stem cell factor (PSCF), which may also be termed porcine “steel” factor, which is preferably membrane-bound PSCF on transfected murine STO feeder cells, for establishing pluripotent or totipotent porcine cell lines, especially for the culture of porcine primordial germ cells (PGCs).
