This book illustrates the advancements made in embryonic cells. The eventual medical employments of embryonic stem cells require methods and protocols to turn these unspecialized cells into fully functioning cell types found in a wide variety of tissues and organs. This book presents an overview of contemporary research on differentiation of embryonic stem cells to a wide variety of cell types, including neural, cardiac cells. Also, induced pluripotent stem cells and other pluripotent stem cell sources have been described. The book will prove to be a valuable resource for engineers, scientists and clinicians as well as students in a wide range of disciplines.
