The eye is the organ that allows us to see the world around us, to discover the light from the environment and transfer the discovered data to the brain. The eye has an intricate structure formed of different specialized parts with a particular job. Main parts of the eye are cornea, lens, retina, optic nerve and retinal pigment epithelium.
Sight is arguably our most important sense; we rely upon it to navigate through our surroundings with ease. Loss of vision can have a huge impact on a person’s life, but many of the disorders that cause blindness are currently difficult or impossible to treat. Researchers are now using stem cell technology to explore possible new approaches to treatments for loss of vision
Stem cells to treat eye disorders:
Eye disorders occur when any of its parts are injured or stops working correctly. The adversity in treating eye conditions is that new biological part for an eye is not easy to acquire. This is where stem cells can be helpful. Stem cells are like a group of new and actively specialized cells that can aid to replace injured or aberrant cells in the eye. Presently there is no therapy to treat neuro degenerative eye conditions but the idea of stem cell transplant to invigorate damaged cells is an enormous appeal.
Disorders or diseases of the eye occur when one or more of these components is damaged, and/or stops working properly. Different disorders develop depending upon which component(s) are not working. The difficulty in treating these problems is that, unlike the electronic parts of a camera, new biological components for the eye are not easy to obtain. This is where stem cell technology may be of use. Stem cells can act as a source of new, healthy specialized cells and may provide a way to replace damaged cells in the eye.
Stem cells can be exploited to produce an endless origin of transplantable cells to treat the eye. Stem cell therapy can work for corneal transplants. Stem cells can safeguard many neurons in the eye which are important for vision. Stem cell therapy has confirmed its potential for retinal deteriorating conditions by producing growth factors in injured neuropil or by replacing the lost cells in the eye. Stem cell therapies come into sight to offer a new promise for the people to regain vision.
Stem cells are full of growth factors that can become pigmented with features of retinal pigment epithelium. Muller stem cells with right growth factors can transform into retinal nerve cells. Stem cells are the trusting cells of the body. Stem cells detached from your own body can be supervised to be eye’s muscle cells, optic nerves, photo-receptor cells or corneal cells, to resume normal function of the eye.
Conclusion: People with molecular deterioration can benefit from stem cell therapy and for loss of vision, research is going on. Profiteering of stem cells still needs a profound understanding of identification of key regulators in photo receptor differentiation pathway. Stem cell research for treating eye conditions are moving along numerous routes.
