Area of Science:

  • Regenerative Medicine
  • Molecular Biology
  • Biotechnology

Background:

  • Gene therapy is a promising strategy for delivering regenerative molecules to bone tissue.
  • Virus-based bone morphogenetic protein (BMP) expression vectors have demonstrated efficacy in stimulating osteoblast differentiation and bone formation.
  • Both in vivo and ex vivo cell transduction can induce bone formation at various anatomical sites.

Purpose of the Study:

  • To explore the potential of gene therapy for bone regeneration.
  • To investigate the synergistic effects of combinatorial gene therapy using BMPs and transcription factors.
  • To examine the role of inducible promoters in controlling gene expression for enhanced bone regeneration.

Main Methods:

  • Utilizing virus-based BMP expression vectors for gene delivery.
