HealthLifestyle Human stem cells ‘help blind rats’ by: – March 8, 2012 12 Views no discussions Share Tweet Sharing is caring! Share More than one in 10 people over the age of 75 have some form of glaucomaStem cells taken from the back of a human eye have restored some vision to blind rats, according to researchers.They say the findings could help treat blindness, caused by glaucoma, if similar results can be repeated in humans.The study, published in the journal Stem Cells Translational Medicine, used the cells to form new nerves in the eye.These hooked up with the existing nerves, restoring sight.Glaucoma can lead to blindness and is caused by a build-up of pressure within the eye. This kills retinal ganglion cells, the nerves which take information from the retina and pass it onto the brain.Researchers at University College London and Moorfields Eye Hospital believe they have regenerated the retinal ganglion cells using human stem cells.With permission from families, cell samples were taken from eyes which had been donated for cornea transplants.Very rare cells in the eye, Muller glia stem cells, were collected. These were grown in the laboratory and converted into retinal ganglion cells.These cells were then transplanted into the eyes of rats without retinal ganglion cells. Before the transplant the rats were blind. Afterwards, electrodes attached to the rats’ heads showed that their brains were responding to low levels of light. One of the researchers Dr Astrid Limb said the new cells were not joining up with the optic nerve as they would normally. Instead they appeared to be “bridging” with other nerves in the retina, which could pass the message on.She said: “Although this research is still a long way from the clinic, it is a significant step towards our ultimate goal of finding a cure for glaucoma and other related conditions.”Prof Peng Khaw, the director of the National Institute for Health Research centre at Moorfields, said: “These results are very exciting. “We see patients with glaucoma whose lives would be transformed with an improvement of only a small percentage of nerve cell function. “The results of these experiments suggest that this may be possible in the future using cells we all have in our own eyes to achieve this.”The study was funded by the Medical Research Council. Its head of regenerative medicine, Dr Rob Buckle, said: “Repair of the eye is an area that is now at the forefront of this field, and this study highlights a new route for delivering the promise of regenerative medicine to treat disabling conditions such as glaucoma.” By James GallagherHealth and science reporter, BBC News Share
BACOLOD City – Amid the coronavirusdisease 2019 outbreak, agrarian reform beneficiary organizations (ARBOs) in thenorthern parts of Negros Occidental shared their resources to their members andother farmers. In a statement on April 2, theDepartment of Agrarian Reform Negros Occidental-I lauded the ARBOs for theirgenerosity towards their fellow farmers and farmworkers, who are considered asfrontliners in food production The financial assistance came from theorganization’s gains from dividends and quedans (warehouse receipts) out oftheir sugarcane harvest in the previous crop year. Hacienda Chambery FarmworkersAssociation has a total of 46 member-ARBs, who acquired a land area of 53hectares under the Comprehensive Agrarian Reform Program (CARP). Member-agrarian reform beneficiaries (ARB) of the Nazareth Farmworkers Association in Barangay Purisima, Manapla, Negros Occidental prepare essential goods and financial aid to be distributed to its members and other ARBs in their area on March 26. They are one of the ARB organizations in this province to do so amid the coronavirus disease 2019 pandemic. DAR NEGROS OCCIDENTAL I-NORTH The group handed out five kilograms ofrice, noodles, sardines and eggs to each recipient. The cooperative has 102 member-ARBs and135 laborers. They cultivate 251 hectares of sugarcane plantation out of the342 hectares acquired area under the CARP. On March 30, the Hacienda Chambery groupin Barangay Caduha-an distributed food packs to 52 recipients, which includesits members, non-member farmers and seasonal farmworkers. Based in Barangay Purisima, the NazarethFarmworkers Association has a total of 63 member-ARBs, who collectively managea seven-hectare sugarcane plantation. In the same village on March 15, the DalayapanAgrarian Reform Cooperative provided a total of 97 sacks of rice to its 237recipients. “This socially responsible and selflessact is what we need today. It reminds us that whether our resources scarce orabundant, we must also consider and be mindful of the needs of others,” itadded.(With a report from PNA/PN) Two ARBOs in Cadiz City, the HaciendaChambery Farmworkers Association and the Dalayapan Agrarian Reform Cooperative,gave out food packs, while the Nazareth Farmworkers Association of Manapla townreleased financial assistance to its members and extended help to other ARBs intheir area. In Manapla town, meanwhile, the NazarethFarmworkers Association released financial assistance to its members andextended help to other ARBs in their area on March 26.
