What is the therapy of retinal stem cells?

different parts of the eye work on the focus of light, which is processed by a membrane called retina. The light is then converted by cells into electrical signals that travel to the brain using an optical nerve. Diseases can damage the retina, causing a person's vision to drop and eventually get lost. The therapy of retinal stem cells is a technique that some scientists examined at the beginning of the 21st century to reverse the damage of such tissues. Several scientists have claimed success in the treatment of animals since 2011 and clinical studies about people can try to find eye conditions such as macular degeneration and retinitis pigmentosa.

embryonic stem cells are usually not characterized as belonging to any type of tissue. Researchers of stem cell therapy often believe that they can develop into the same tissues in which they are located. The retina usually consists of several different types of cells. Scientists have found cells of retinal progenitors in which they can develop special types thatThey are needed, but they must be injected. Cell types in retina usually include ganglia cells and photoreceptors.

In the research, different types of stem cells were used. Scientists have worked with several of them to try to find out which ones are the best for retinal stem cell therapy. One species seems more suitable for the treatment of retinal injury, while the other is considered less likely that the body's immune system is rejected. Scientists in animal studies have argued that they can integrate with other cells into retinal and nerve fibers. Stem cells for adults were also analyzed; They are usually specific to certain organs, but some research suggests that they can be used on the retina.

Therapy of retinal stem cells can be done with a needle. While usually the most non -invasive approach, success often depicts on cells migrating to the right place. Technique called SubreTinal injections are usually more difficult, but stem cells are generally located closer to the selected area. Experiments have often shown that there is more likely to be distinguished. The death of cells may be a problem in experiments, and some scientists have tried to supply stem cells to polymer graft to obtain the maximum number to survive.

The challenge of stem cell treatment in the eye may be to integrate into the tissue. Sometimes cell division is also inhibited, while the reactions of the immune system may also disable successful treatment. The treatment of retinal stem cells in animals was sometimes successful at the beginning, but visual procedure can degrade over time, as shown in some scientific studies.
