History of Human
Embryonic Stem Cell Research

Human blastocyst
      • In 1998, James Thomson (University of Wisconsin-Madison) isolated cells from the inner cell mass of the early embryo, and developed the first human embryonic stem cell lines.
      • In 1998, John Gearhart (Johns Hopkins University) derived human embryonic germ cells from cells in fetal gonadal tissue (primordial germ cells).
      • Pluripotent stem cell “lines” were developed from both sources
