Current topics in developmental biology. Volume 47, Somitogenesis. Part I /
The chapters contained in this two-volume set provide a broad perspective on the novel strategies and conceptual paradigms that drive the current resurgence of interest in somitogenesis - the process by which somites form and elaborate differentiated tissues and structures. Because somites are a ubi...
