| الوصف: | Introduction: Cell-based bone regenerative therapy exhibits considerable potential in the treatment of bone defects caused by trauma, disease, and congenital anomalies. The periosteum, a fibrous membrane covering the outer surface of bone, plays a crucial role in bone formation and regeneration by sourcing osteoprogenitor cells. The remarkable osteogenic potential of periosteal cells (PCs) has led to the effective clinical implementation of PC-based regenerative therapies and tissue engineering. The abundance of progenitor cells in cultured PCs is well established; however, the heterogeneity of the cell population and its impact on bone regeneration remain uncertain. In this study, we aimed to characterize the heterogeneity of cultured PCs via single-cell RNA-sequencing (scRNA-seq) and to examine their osteogenic potential in vivo. Methods: Human PCs cultivated using the tissue explant method were utilized in this study. scRNA-seq and real-time PCR were performed to examine the cellular heterogeneity and osteogenic capacity of the cultured PCs. Experimental bone formation by the cultured PCs was examined using the rat model of subcutaneous implantation. Results: ScRNA-seq analysis showed that the cultured PCs were categorized into three cell types (osteoprogenitor cells, mesenchymal stem cells, and fibroblasts) with specific gene expression patterns. In addition, the cellular population and osteogenic capacity differed between the central and peripheral regions in the culture dish. The PCs in the central region showed higher osteogenic potential than those in the peripheral region. Conclusions: This study revealed the diversity of the composition of the PCs and their distinct osteogenic capabilities in different regions in the culture dish. The findings may provide promising prospects for the development of more efficacious regenerative therapeutic applications using cultured PCs in the future. |
