CD30 and its ligand: Possible role in regulation of teratoma stem cells

Abstract

Like the oocyte, the cells of the early embryo, and primordial germ cells, human teratocarcinoma stem cells are pluripotent, capable of giving rise to a wide range of somatic and extraembryonic tissues. Growth factors which regulate the growth of multipotent stem cells in the mouse have been identified, but none of these have been shown conclusively to have similar effects on human or primate multipotent stem cells. CD30 is a member of the tumour necrosis factor receptor superfamily with a restricted pattern of tissue distribution, limited to immune cells, decidual tissue, and human embryonal carcinoma: in common with other embryonal carcinoma markers, CD30 is found in foci of cells in a sub..
