Currently, there is a lack of comprehensive understanding of the microenvironmental factors involved in ORNJ. In this study, we reveal the activation of taurine metabolism in irradiated mandibular stromal cells using scRNA-Seq and demonstrate a decrease in taurine levels in irradiated bone marrow mesenchymal stromal cells (BMSCs) through metabolomics.
