Scientists from Anglia Ruskin University in England used nanotechnology to grow human retina cells. Researchers have created a tiny 3D scaffold in which pigment epithelial cells can remain healthy and viable. In this respect reports SciTechDaly.
To create a scaffold for cells, scientists used polyacrylonitrile and jeffamine polymers, which break down into ultrathin fibers using an electric field. These substances have high mechanical strength and miscibility with water. The samples were then coated with the anti-inflammatory steroid fluocinolone acetonide.
It turned out that this structure increases the growth and functionality of visual cells. Scientists grew pigment epithelial cells on the created surface that survived for 150 days. The pigment epithelium is the outermost layer of the retina, which performs functions related to nutrition and metabolism among the structures of the eye and general blood flow. This layer of cells also provides the clarity and contrast of the images the person sees.
The new technology will advance the treatment of age-related molecular degeneration (AMD). This is a disease that affects the central area of the retina (macula), leading to loss of central vision. It is believed that replacing retinal cells can restore lost vision. Scientists are now conducting research to understand how to transplant a framework containing adult cells into the human eye socket.
