Stem Cells

Washington, September 18 (ANI): US researchers may have moved a step further towards gaining a deeper understanding of the role of stem cells in liver cancer.

A team of experts from Penn State College of Medicine and the University of Southern California used a unique approach [...]

Washington, Sep 18 (ANI): Scripps Research Institute scientists have offered new hope for parents whose children suffer from the rare genetic disorder ‘cystinosis’ by showing through an experiment on mice that stem cell transplantation [...]

London, Sept 14 (ANI): Scientists at the European Molecular Biology Laboratory (EMBL) have identified two proteins that prompt stem cells to develop into skin cells.

They hope that the new findings could help understand basic mechanisms involved not only in formation of skin, but also on skin cancer and other epithelial cancers.

According to lead researcher Claus [...]

London, Sep 14 (ANI): British scientists have identified the master gene, called E4bp4, that causes blood stem cells to turn into disease-fighting ‘Natural Killer’ (NK) immune cells.

The discovery, by researchers at Imperial College London, UCL and the Medical Research Council’s National Institute for Medical Research, could one day help scientists boost the body’s production of [...]

Washington, Sep 9 (ANI): A lung cancer oncogene, called PKCiota, is necessary for the proliferation of lung cancer stem cells, and turning it off could act as a key for the treatment of this deadly disease, according to scientists at the Mayo Clinic campus in Florida.

These stem cells are rare and powerful master cells that [...]

London, August 31 (ANI): British surgeons at the Spire Hospital in Southampton are using a novel technique that uses stem cells to repair damaged bones.

Media reports on this procedure suggest that it may prevent thousands of people from needing to have an artificial hip fitted.

Mark Venables, 39, is one patient on whom doctors at the [...]

Washington, Aug 29 (ANI): While it gets quite difficult to manipulate tiny objects like single cells or nanosized beads via relatively large, unwieldy equipment, Penn State engineers have now designed a new system that uses sound as a pair of tiny tweezers that are small enough to place infinitesimal objects on a chip.

While optical tweezers [...]

Washington, Aug 28 (ANI): Scientists have long asserted that females are born with their entire lifetime’s supply of eggs, and once they’re gone, they’re gone. However, a new study suggests that in case of nematode worms, this does not hold true.

The findings by researchers at Fred Hutchinson Cancer Research Center have been published online Aug. [...]

Washington, Aug 27 (ANI): Scientists in Switzerland have discovered a novel way to inhibit the growth of human colon cancer cells and preventing the disease from reaching advanced stages and the development of liver metastases.

The study shows that blocking the so-called Hedgehog-GLI pathway can prevent the growth of tumours, metastatic lesions and cancer stem cells, [...]

Washington, August 18 (ANI): University College London scientists have shown that it is possible to guide stem cells to sites of cardiovascular injury using microscopic magnetic particles, in a new method designed to increase the capacity of cells to repair damaged tissue.

Writing about their achievement in The Journal of the American College of Cardiology: Cardiovascular [...]

Washington, Aug 14 (ANI): In a groundbreaking discovery that may eventually render bypass surgery history, researchers at Tel Aviv University have shown that an injected protein can regrow blood vessels in the human heart.

In heart disease, blood vessels are either clogged or die off, starving the heart of oxygen and leaving it highly susceptible to [...]

Washington, August 14 (ANI): An Indian-origin researcher in Boston has announced the discovery of a chemical that works in mice to kill the rare, but aggressive, cells within breast that have the ability to seed new tumours.

Piyush Gupta, a researcher at the Broad Institute, points out that these cells, known as cancer stem cells, are [...]

Washington, Aug 12 (ANI): In a novel study, University of Central Florida researchers have shown that light energy can be used to harness the healing power of stem cells and guide them to areas of the body that need help.

Lead researcher Aristide Dogariu, an optical scientist at the College of Optics and Photonics, and Kiminobu [...]

Washington, Aug 7 (ANI): John Hopkins researchers have identified a powerful set of cells in bladder tumours that appears to be primarily responsible for the cancer’s growth and spread.

The researchers have long suspected that a subset of cells in cancerous tumours act much like developmentally primitive [...]

Washington, Aug 4 (ANI): Stanford’s School of Medicine researchers have identified the first human bladder cancer stem cell.

“This is first time we’ve found this ‘don’t eat me signal’ in a stem cell of a solid cancer,” said Irving Weissman, MD, the Virginia and D.K. Ludwig Professor for Clinical Investigation in Cancer Research at the [...]

Washington, Aug. 3 (ANI): The “daughters” of breast stem cells, called luminal progenitor cells, are found to be responsible for breast cancers that develop in women carrying mutations in the gene BRCA1, according to scientists at Walter and Eliza Hall Institute.

Women with BRCA1 mutations often develop “basal-like” breast cancer, which is a particularly aggressive form [...]
