The study of the processes through which plants and animals grow and develop is referred to as developmental biology. It encompasses various areas of study such as biology of regeneration, metamorphosis, asexual reproduction as well as the growth of stem cells in the adult organisms. The developmental processes of organisms are divided into two major categories, namely, cell differentiation and regeneration. The process in which different functional cell types arise during development is known as cell differentiation. The ability to regrow a missing part is known as regeneration. Some of the other processes studied within this field are regional specification, morphogenesis and growth. This book unfolds the innovative aspects of developmental biology which will be crucial for the progress of this field in the future. The topics included herein on this subject are of utmost significance and bound to provide incredible insights to readers. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
