| Outline of Final Research Achievements |
The purpose of this study is to elucidate the molecular basis of cell fate decisions in the bone and to identify new bone formation-promoting factors that control reactivation of bone lining cells. Venus-positive cells were isolated from transgenic mice that express yellow fluorescence protein Venus under the control of bone specific promoter and subjected single-cell RNA-sequencing to comprehensively profile the mRNA populations. All cells expressed osteoblast markers, and some cells showed a characteristic gene expression patterns that observed in bone lining cells. In addition, some cells expressed the genes that crucial for adipocyte differentiation. Thus, Venus-positive cells appear to comprise a heterogeneous cell population that may underlie the diversity in transcriptional profiles.
