Peptide derived from stromal cell-derived factor 1δ enhances the expression of osteogenic proteins bone marrow stromal cell differentiation and promotes bone formation in models.

Mesenchymal stem cells (MSCs) rely on chemokines and chemokine receptors to execute their biological and physiological functions. Stromal cell-derived factor-1 (SDF-1) is upregulated in injury sites, where it acts as a chemotactic agent, attracting CXCR4-expressing MSCs, which play a pivotal role in the healing and regeneration of tissue throughout the body. Furthermore, SDF-1 expression has been observed in regions experiencing inflammation-induced bone destruction and fracture sites.

Surgical Excision for Refractory Ischiogluteal Bursitis: A Consecutive Case Series of 21 Patients.
