Precious Cargo: delivery of stem cells for retinal degeneration
Retinal degeneration is the cause of many diseases such as retinitis pigmentosa and age-related macular degeneration (AMD), which ultimately lead to blindness. This animation from The Angiogenesis Foundation explains the progression and symptoms of AMD.
While these diseases are difficult to prevent, they're even trickier to cure. The article "Scaffolds and stem cells: delivery of cell transplants for retinal degenerations" reviews the ongoing research in regenerating damaged retinal tissue. Here is an outline of the article:
