Evaluating Human Embryonic Germ Cells: Concord and Conflict as Pluripotent Stem Cells
Stem Cells, 2005 AbstractThe realization of cell replacement therapy derived from human pluripotent stem cells requires full knowledge of the starting cell types as well as their differentiated progeny. Alongside embryonic stem cells, embryonic germ cells (EGCs) are an alternative source of pluripotent stem cell. Since 1998, four groups have described the derivation of
