Duke Engineers Grow New Blood Vessels for Eyes
30 Jun
Summary
- Duke University engineers cultivated specialized retinal blood vessel cells from stem cells.
- These lab-grown cells successfully restored retinal function in mouse models.
- The breakthrough could lead to new treatments for millions affected by vision loss.
Biomedical engineers at Duke University have successfully cultivated specialized retinal endothelial cells from induced pluripotent stem cells (iPSCs). This pioneering work addresses a significant challenge in treating retinal vascular diseases, which affect millions globally.
These lab-grown cells, when introduced into mouse models of retinal disease, demonstrated the ability to integrate into compromised tissue. The research showed successful regeneration of blood vessels and restoration of retinal function in the animal subjects.
This advancement offers a potential solution for the limited and costly availability of current retinal endothelial cell sources. The ability to grow these cells from iPSCs could significantly lower expenses and increase consistency for therapeutic development.
The Duke team's research also created a robust in vitro model of diabetic retinopathy, a leading cause of vision loss. This model allows for better understanding of disease mechanisms and accelerated drug discovery and testing.
With a patent pending for their stem cell-based therapeutics and modeling techniques, the researchers are exploring industry partnerships to bring these innovations to clinical applications.
