Retroviral vector-mediated gene transfer into endothelial cells

Area of Science:

• Biotechnology
• Molecular Biology
• Cell Biology

Background:

• Retroviral vectors have been utilized for stable gene transfer into endothelial cells.
• In vitro studies have transduced endothelial cells with therapeutic genes like growth hormone and tissue plasminogen activator (t-PA).
• In vivo studies demonstrated recombinant gene expression in endothelial cells using the lacZ marker gene.

Purpose of the Study:

• To review the current state of retroviral vector-mediated gene transfer in endothelial cells.
• To highlight the potential therapeutic applications and challenges for clinical protocols.
• To emphasize the underutilized potential of retroviral vectors for studying endothelial cell biology.

Main Methods:
