This book describes how stem cells regenerate any damaged tissues, including cutaneous wounds as well as the cornea, musculoskeletal tissue, heart, and other organs. This book focuses on stem cell-mediated secretory factors, how those factors actually mediate the regeneration process for successful regeneration of the tissue. Readers will discover what signaling processes are involved in the regeneration process, and whether they are different depending on the origin of the tissues, and also the intracellular mechanism that aids in successful regeneration. This is an ideal reference for graduate students and post-doc researchers and faculty interested in the research and delivery of stem cells for regenerative therapy.
