USA – Blind Mice Sense Light Thanks to Stem Cells

Image via Wikipedia

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

Korea Closer to Cloning Embryonic Stem Cells

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

SOUTH KOREA – South Korea also relaunches embryonic stem cell research

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

Transplants: human-pig embryos from stem cells

Scientists have for the first time grown embryos that contain a combination of pig and human stem cells, in a step toward one day growing transplantable organs, a study said on Thursday.

However, the research remains at a very early stage and proved more difficult than expected, the researchers reported in the peer-reviewed journal Cell.

“This is an important first step,” said lead investigator Juan Carlos Izpisua Belmonte, a professor in the Salk Institute of Biological Studies’ Gene Expression Laboratory.

“The ultimate goal is to grow functional and transplantable tissue or organs, but we are far away from that.”

ITALY – Stem cells from amniotic liquid, new hopes

Image via Wikipedia

Stem cells found in the amniotic liquid represent new hopes to treat diseases. For the 13th World Congress on Human Reproduction, which is taking place in Venice, Biocell and Toma, two companies based in the Lombardy region active in the field of prenatal diagnosis and biotechnology, today are presenting the results of research conducted by their scientific staff entitled “Characterization and cryoconservation of mesenchymal stem cells from the amniotic liquid”.

“Every day the amniotic liquid reveals its potential as a source of mesenchymal stem cells, creating increasing interest in the field of regenerative medicine,” said Professor Simoni,
