Stem cell discovery could eliminate need for embryo research and usher in human cloning

Any cell can be rewound to a pre-embryonic state, according to stem cell researchers. Scientists in Japan and at Harvard said they found that stem cells, which can transform into any tissue and potentially regenerate the body, could be quickly made by dipping blood cells into an acid bath or…

Vatican-backed ‘VSEL’ alternative to stem cells found to be a fraud

Scientists at Stanford University School of Medicine issued a report this month that said a type of stem-cell alternative approved by the Vatican and other theologians has turned out to be a myth. According to an essay by bioethicist Arthur Caplan, Dr. Irving Weissman and his team have concluded that…

Scientists ‘print’ 3D object with stem cells

Scientists on Monday said that for the first time they had printed 3D objects using human embryonic stem cells, furthering the quest to fabricate transplantable organs. Once fine-tuned, the technology should allow scientists to make three-dimensional human tissue in the lab, eliminating the need for organ donation or testing on…

Stem cell implants boost monkeys with Parkinson’s

Monkeys suffering from Parkinson’s disease show a marked improvement when human embryonic stem cells are implanted in their brains, in what a Japanese researcher said Wednesday was a world first. A team of scientists transplanted the stem cells into four primates that were suffering from the debilitating disease. The monkeys all had violent shaking…

First patients shown to improve with embryonic stem cells

NEW YORK (Reuters) – Before treatment, the 51-year-old graphic artist was legally blind, unable to read a single letter on a standard eye chart. She has suffered from Stargardt’s disease, the most common form of macular degeneration in young patients, since she was a teenager, and it was getting progressively worse. A…

Study confirms groundbreaking advance in stem cells

PARIS — The first use of embryonic stem cells in humans eased a degenerative form of blindness in two volunteers and showed no signs of any adverse effects, according to a study published by The Lancet on Monday. Publication in the peer-reviewed journal marks an important step for embryonic stem…

First mixed-embryo monkeys are born in U.S.

WASHINGTON — US researchers said Thursday they have created the world’s first mixed-embryo monkeys by merging cells from up to six different embryos, in what could be a big advance for medical research. Until now, rodents have been the primary creatures used to make chimeras, a lab animal produced by…

First U.S. embryonic stem cell trial is halted

The first-ever trial using human embryonic stem cells to treat paralysis has been halted due to high costs and the company will focus instead on new cancer treatments, Geron said Tuesday. The California-based biotech firm, which had bypassed federal funding to get its pioneering but controversial trial off the ground in October…

Scientists use cloning to make human stem cells

CHICAGO (Reuters) – U.S. scientists for the first time have used a cloning technique to get tailor-made embryonic stem cells to grow in unfertilized human egg cells, a landmark finding and a potential new flashpoint for opponents of stem cell research. The researchers were trying to prove it is possible…

Experts grow mouse sperm to help with human infertility

HONG KONG (Reuters) – Researchers in Japan used embryonic stem cells to grow healthy mouse sperm on laboratory dishes, a development which could help treat human infertility, they said Friday. The finding, published in the journal Cell, marks a step forward for using stem cells for regenerative medicine. Stem cells…
