• HOXB4 Enhances MSC Protection via Wnt/β-Catenin in Lung Inju

  2026-04-12

  This study demonstrates that overexpression of HOXB4 in bone marrow mesenchymal stem cells (BMSCs) confers significant protection against lipopolysaccharide-induced endothelial injury, a model of acute lung injury, by activating the Wnt/β-catenin pathway. Use of the pathway inhibitor XAV-939 revealed that this protective effect is at least partially dependent on Wnt/β-catenin signaling, offering mechanistic insight into potential strategies for improving MSC-based therapies in inflammatory lung disease.
