Advances and challenges in intravital imaging of craniofacial and dental progenitor cells
Craniofacial and appendicular bone homeostasis is dynamically regulated by a balance between bone formation and resorption by osteoblasts and osteoclasts, respectively. Despite the developments in multiple imaging techniques in bone biology, there are still technical challenges and limitations in the investigation of spatial/anatomical location of rare stem/progenitor cells and their molecular regulation in tooth and craniofacial bones of living animals. Recent advances in live animal imaging techniques for the craniofacial and dental apparatus can provide new insights in real time into bone stem/progenitor cell dynamics and function in vivo. Here, we review the current inventions and applications of the noninvasive intravital imaging technique and its practical uses and limitations in the analysis of stem/progenitor cells in craniofacial and dental apparatus in vivo. Furthermore, we also explore the potential applications of intravital microscopy in the dental field.
期刊介绍：
As of January 2000, Developmental Genetics was renamed and relaunched as genesis: The Journal of Genetics and Development, with a new scope and Editorial Board. The journal focuses on work that addresses the genetics of development and the fundamental mechanisms of embryological processes in animals and plants. With increased awareness of the interplay between genetics and evolutionary change, particularly during developmental processes, we encourage submission of manuscripts from all ecological niches. The expanded numbers of genomes for which sequencing is being completed will facilitate genetic and genomic examination of developmental issues, even if the model system does not fit the “classical genetic” mold. Therefore, we encourage submission of manuscripts from all species. Other areas of particular interest include: 1) the roles of epigenetics, microRNAs and environment on developmental processes; 2) genome-wide studies; 3) novel imaging techniques for the study of gene expression and cellular function; 4) comparative genetics and genomics and 5) animal models of human genetic and developmental disorders.
genesis presents reviews, full research articles, short research letters, and state-of-the-art technology reports that promote an understanding of the function of genes and the roles they play in complex developmental processes.
