Researchers map the first complete atlas of single cells that make up the human teeth Researchers at the University Zurich have mapped the first complete atlas of single cells that make up the human teeth. Their research shows that the composition of human dental pulp and periodontium vary greatly. Their findings open up new avenues for cell-based dental therapeutic approaches. During the last 30 years, medical and dental research has attracted a large number of scientists and practitioners working on aspects of high medical relevance that involve a combination of genetic and tissue regeneration approaches. These developments in stem cell and tissue engineering have provided medical and dental researchers with new insights and given rise to new ideas as to how everyday clinical practice can be improved. Many research groups are dealing with questions like: How can we help injured tissues and organs heal? Can lost tissue be regenerated? How can we create solid protocols that apply across all stem cell therapies?
