…they could transform medicine, providing treatments for blindness, spinal cord and other severe injuries, and new cells for damaged organs. The Sanger Institute research is focused on two main forms: 1. embryonic stem cells, which are harvested from embryos, 2. reprogrammed cells, also known as induced pluripotent stem cells (iPS cells), which are reprogrammed from ordinary skin or blood cells. i…
…lymphocytic leukemia and infected their T cells with the virus. When they infused the blood back into the patients, the engineered T cells successfully eradicated cancer cells, multiplied to more than 1,000 times in number and survived for months. They even produced dormant “memory” T cells that might spring back to life if the cancer was to return. On average, the team calculat…

After three weeks about one in 10 of the cells became neural precursor cells. Lead researcher Prof. Marius Wernig said: “We are thrilled about the prospects for potential medical use of these cells. “We’ve shown…

However, injecting stem cells into 17 day-old mice saw a huge increase in their lifespans – from an average of just 21-28 days to more than 66 days, three times longer than usual. The modified mice given stem cell shots grew alm…
Researchers have discovered the cells in tumors that seem to be responsible for their re-growth. Three separate studies on mice appear to have confirmed the view that the growth of tumors is driven by so-called cancer stem cells. The researchers claim to have resolved one of the biggest controversies in cancer research and say their work marks a “paradigm shift” in the field. The stud…
…IV from an infected patient. Much HIV research focuses on vaccines or drugs that slow the virus’s progress – but this new technique could offer hope of a “cure”. The study, published April 12 in the journal PLoS Pathogens, demonstrates for the first time that engineering stem cells to form immune cells that target HIV is effective in suppressing the virus in living tissues. “We believe…

Israeli scientists say they have managed to turn patients’ own skin cells into healthy heart muscle in the lab. Ultimately they hope this stem cell therapy could be used to treat heart failure patients. As the transplanted cells are from the individual patient this could avoid the problem of tissue rejection, they told the European Heart Journal. Early tests in animals proved promising but…

Israeli scientists warn that sitting down for too long may give you a big bottom. Not just eating junk food put your bottom at risk – sitting all day in the office is just as likely to broaden your rear. The warning comes from a scientist who usually researches bed sores which can affect those bedridden or in a wheelchair due to paralysis. Israeli scientists warn that sitting down for too long m…
Stem cells made from skin have become “grandparents” after generations of life were created in experiments by scientists in Japan. The cells were used to create eggs, which were fertilized to produce baby mice. These later had their own babies. If the technique could be adapted for people, it could help infertile couples have children and even allow women to overcome the menopause. Bu…

An international research team has shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life. Viruses cannot replicate on their own; they must hijack other cells and turn them into virus production factories. The study, published in Nature Immunology, showed how some parts of the immune system destroy their own raw materials, stopping HIV. It…

British researchers have shown that a tumor-killing virus can sneak around the body by "hitchhiking" on the back of blood cells A study in 10 people at the University of Leeds and The Institute of Cancer Research, at the Royal Marsden Hospital, showed that the virus could escape the immune system by hiding in the blood. All the patients…

However, in about one in 10 people with profound hearing loss, nerve cells which should pick up the signal are damaged. It is like dropping the baton after the first leg of a relay race.

Scientists in the US have created a free swimming artificial jellyfish using silicone as a base on which to grow heart muscle cells that were harvested from rats. They used an electric current to shock the Medusoid into swimming with synchronized contractions that mimic those of real jellyfish. The advance, by researchers at Caltech and Harvard University, is reported in the journal Nature Biotec…
A new study suggests that chemotherapy can undermine itself by causing a rogue response in healthy cells, which could explain why people become resistant. The treatment loses effectiveness for a significant number of patients with secondary cancers. Writing in Nature Medicine, US experts said chemo causes wound-healing cells around tumors to make a protein that helps the cancer resist treatment….

It went down to 16% after six months and 12% after a year. Healthy heart muscle appeared to take its place. The study said the cells “have an unprecedented ability to reduce scar and simultaneously stimulate t…

Vitamin B3 could be the new weapon in the fight against resistant bugs such as MRSA, a new research has suggested.
