The book "Dental Pulp Stem Cells" by Sibel Yildirim offers a comprehensive analysis of the latest developments in stem cell research, particularly regarding the use of dental stem cells from dental pulp. In recent years, stem cell technology has made remarkable progress, expanding our understanding of cell biology and challenging fundamental paradigms in research. The book highlights the development of teeth from ectoderm and ectomesenchyme and discusses the multipotent properties of dental stem cells, which can be obtained from both permanent and deciduous teeth. These cells are of great interest to regenerative medicine due to their high availability, immunocompatibility, and ability for in vitro expansion. Despite these advancements, many questions and controversies remain in this research area, which are addressed in this work.
