History of the germ cells and early embryology of certain aphids: George Washington Tannreuther: Books. An embryo is an early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development refers to the portion of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs. Stem cells have fascinated both biologists and clinicians for over a century. Here, we discuss the origin of the term stem cell, which can be traced back to the late 19th century. The term stem cell originated in the context of two major embryological questions of that time: the continuity of the germ-plasm and the origin of the History of the Germ Cells and Early Embryology of Certain Aphids from Dymocks online bookstore.
