We have heard a great deal about stem cell research and countries like America , Japan , China , Europe ,Thailand and Singapore are pursueing unabatedly to use its applications for curing several diseases in the world.
China and Thailand have gone beyond the stage of research and even leapfrogged to the actual use of the method to try and cure despite the danger of side effects which can be determined only after several years of clinical trials.Many Westerners strickened with diseases that Western doctors have no cure at the moment braved the ordeal of using stem cells believing the method can provide the answer to their quest for a cure.
The West is more cautious and it could possibly be another 10 years before such operations can be performed on debilitating diseases like cancer, heart complications and liver problems due to the requirements imposed by the Health Authorities.
However diseases like the loss of vision or blindness could possibly be carried out as such operation does not precariously cause the loss of lives. Blindness is an eye related disease that has affected millions in the world. While some blindness can be cured like cornea infections or even glaucoma, doctors are dumbfounded when confronted with diseases like age-related mascular degeneration, retinitis pigmentosa, diabetes and 100 other types that affect the eye as there is presently no cure. Doctors can only monitor the degeneration of the eyes.
However, stem cell research have given some hope to people who are blind caused by diseases of the retina. Dr. Michael Young of the Schepens Eye Research Institute and Harvard University discovered from his experiments that stem cells can regenerate the damaged retina .In an experiment on rats caused by bad genes he injected neural stem cells in the retina .Once in the retina the stem cells begin to move over to the damaged retina and transform it to a normal looking retina cells complete with the nerve fibers which joins to the optic nerves.
The experiment has not reached the final stage where the procedure can be adopted as the stem cells injected are not light detectors and until further advances are made to make the regenerated retina successfully transmit to the brain for an optical vision more experiments have to be conducted before the procedure is adopted.
Dr. Michael Young’s work when successful will help millions of people with eye related diseases in the world to see again giving them the vision and stop their suffering of living in the dark.
