The study of processes that enables plants and animals to grow and develop is known as developmental biology. Developmental biology includes the biology of asexual reproduction, regeneration and metamorphosis. It also studies the growth of stem cells in adult organisms. Some of the major processes of embryonic development studied in this discipline are morphogenesis, tissue growth, cell differentiation and regional specification. The developmental processes of organisms studied in this discipline are mainly divided into two categories: cell differentiation and regeneration. Cell differentiation is the development of different functional cell types. Regeneration refers to the ability to regrow a missing part. This book strives to provide a fair idea of this discipline and to help develop a better understanding of the latest advances within the field. It also unfolds the innovative aspects of developmental biology, which will be crucial for the progress of the field in the near future. Scientists and students actively engaged in this field will find this book full of crucial and unexplored concepts.
