Abstract (original English)

Tendon injuries cause pain and functional limitations, posing a clinical burden due to poor healing and recurrence. Combining mesenchymal stem cells (MSCs), tissue-specific extracellular matrix (ECM) scaffolds, and bioactive factors may enhance tendon regeneration. This study investigated integrating adipose-derived MSCs (AD-MSCs) seeded on a decellularized tendon scaffold (DTS) with G-CSF injection for tendon repair. DTS was prepared from rat Achilles tendons through freeze-thaw cycles and sodium dodecyl sulfate decellularization, preserving ECM structure. In vitro, AD-MSC viability, tenogenic gene expression, and scratch wound closure were assessed in response to G-CSF ± DTS. In vivo, a rat Achilles tendon defect model included: control (CTL), DTS, DTS with G-CSF, and DTS and AD-MSCs with G-CSF. After 6 weeks, histology, immunohistochemistry, collagen quantification, gene expression, and immunofluorescence analyses were performed. DTS maintained AD-MSC viability and tenogenic differentiation in vitro by upregulating SCX, COL1, and TN-C. G-CSF (1000 ng/mL) enhanced AD-MSC-mediated wound closure in the presence of DTS extract. In vivo, DTS with AD-MSCs and G-CSF showed organized collagen alignment, reduced cellularity and inflammation, increased collagen deposition, and the highest total collagen content. Furthermore, it exhibited upregulation of SCX, TN-C, COL1, THBS-4, and DC
