- The study explores the EphB4/ephrinB2 signaling pathway's role in enhancing osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) and M2 macrophage polarization.
- Direct co-culture of hPDLSCs and M0 macrophages at a 5:1 ratio significantly promoted osteogenic differentiation and M2 polarization, evidenced by increased ALP activity, mineralization, and anti-inflammatory factors.
- Pharmacological interruption of the EphB4/ephrinB2 pathway reduced hPDLSC osteogenic differentiation, M2 polarization, and p-STAT3 expression, suggesting the pathway's regulatory role via STAT3 signaling.
- The findings highlight the potential of targeting the EphB4/ephrinB2 pathway for periodontal tissue regeneration by modulating immune responses and stem cell differentiation.
