The effective and translational strategy to regenerate knee meniscal fibrocartilage remained challenging. Herein, we first identified vascular smooth muscle cells (VSMCs) transdifferentiated into fibrochondrocytes participated in spontaneous regeneration using cell lineage tracing transgenic mice defect model. Then, low-intensity pulsed ultrasound (LIPUS) acoustic stimulus enhanced fibrochondrogenic transdifferentiation of VSMCs vitro vivo. Mechanistically, LIPUS could up-regulate mechanosensitive ion channel Piezo1 expression then activate the transforming growth factor β1 (TGFβ1) signal, following repression Notch consequently enhancing VSMCs. Finally, demonstrated that regular anisotropic native-like tissue a beagle canine subtotal meniscectomy model at 6 months postoperatively. single-cell RNA sequencing analysis confirmed role VSMC regeneration.
