British regulators have given Moorfields approval to begin trials using retinal cells derived from human embryonic stem cells (hESCs).
Twelve patients with Stargardt’s disease will have the cells injected into the eye. You can read more about the trial here.
Although there is great excitement about the trial, Julia knows that the initial phase will simply check safety (…)
“It would be marvellous if I could get some of my sight-loss reversed”, said Julia. “Even if it simply halts the deterioration, that would be great. And the real benefit would be for children. It could mean they don’t need to lose any
Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease.
Dr. Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins.

Human embryonic stem cells implanted into mice specifically engineered to have a serious retinal dysfunction resulting in blindness have restored the animal’s capacity to sense light during tests.
The results, published in international magazine, Cell Stem Cell, were obtained in the United States by a research group in the Department of Biological Structure at the University of Washington in Seattle. The study, performed by Deepak Lamba, Juliane Gust, and Thomas Reh, demonstrated that it is possible to obtain retina progenitor cells from stem cells derived from the embryo. The researchers observed, “In principle, embryonic stem

Korean scientists are moving closer to cloning embryonic stem cells, the unprecedented breakthrough that their compatriot and disgraced scientist Hwang Woo-suk claimed to have achieved in 2004, only to have this disproved later.
Currently, a team at the Cha Medical Center is working on a project after getting state approval last year, while another team headed by professor Park Se-pill at Jeju National University is also set to begin research.
Park and his associates are awaiting final approval from the National Bioethics Committee.
“If the endorsement is made before June, we should be able to clone human embryonic stem cells

After the decision of the United States to remove the ban preventing stem cell researchers from using public funding for experiments, legislators in South Korea have been put under pressure by scientists who have been aspiring to do experiments on stem cells from cloned human embryos.
Up until a few weeks ago the National Bioethics Committee continued to postpone a decision on the matter, but now thanks to the American president, it is increasingly probable that at most, by the end of April, researchers of the Cha Medical Institute of Seoul will be able to resume
