"Induction and Patterning of the Primitive Streak, an Organizing Center of Gastrulation in the Amniote" (2004), by Takashi Mikawa, Alisa M. Poh, Kristine A. Kelly, Yasuo Ishii, and David E. Reese

?Induction and Patterning of the Primitive Streak, an Organizing Center of Gastrulation in the Amniote,? (hereafter referred to as ?Induction?) examines the mechanisms underlying early amniote gastrulation [7] and the formation of the primitive streak [8] and midline axis. The review, authored by Takashi Mikawa and colleagues at Cornell University [9] Medical College, was published in Developmental Dynamics in 2004. The article primarily discusses chick [10] embryos as a model organism [11] for nonrodent amniote gastrulation [7], although it intermittently touches on nonamniote gastrulation [7] for comparative purposes. ?Induction? attempts to explain the initiation of cell differentiation [12] and embryo organization [13], one of the most intriguing processes of embryology [14].
