New system to deliver siRNA into primary cells

In technology that promises to one day allow drug delivery to be tailored to an individual patient and a particular cancer tumor, researchers at the University of California, San Diego School of Medicine, have developed an efficient system for delivering siRNA into primary cells.

Discovery of method to neutralize tumor growth in embryonic stem cell therapy

Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells. Their work paves the way for further progress in the promising field of stem cell therapy.

Significant advance in generating induced pluripotent stem cells

In a paper publishing online April 23rd in Cell Stem Cell , a Cell Press journal, Dr. Sheng Ding and colleagues from the Scripps Research Institute in La Jolla, California, report an important step forward in the race to make reprogrammed stem cells that may be better suited for use in clinical settings.

Breakthrough in generating safer, therapeutic stem cells from adult cells

The new technique solves one of the most challenging safety hurdles associated with personalized stem cell-based medicine because for the first time it enables scientists to make stem cells in the laboratory from adult cells without genetically altering them.

Cells from human blood can morph into stem cells

In a recent study, U.S. researchers have reprogrammed cells found in circulating blood into cells that are molecularly and functionally indistinguishable from embryonic stem cells, a revolutionary achievement that provides a readily accessible source of stem cells and an alternative to harvesting embryonic stem cells.

New nucleotide could revolutionize epigenetics

Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine - the A,T,G and C that make up the DNA code.

Creating ideal neural cells for clinical use

Investigators at the Burnham Institute for Medical Research (Burnham) have developed a protocol to rapidly differentiate human embryonic stem cells (hESCs) into neural progenitor cells that may be ideal for transplantation.

microRNAs manipulate cells to one day create safe embryonic-like stem cells

A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state.

Human embryonic stem cells may revolutionize the treatment of oral diseases

Human embryonic stem cells (hESC) provide a potentially unlimited source of oral mucosal tissues that may revolutionize the treatment of oral diseases.

What are the next steps for embryonic stem cell research?

A new report on embryonic stem cell research from The George Washington University School of Public Health and Health Services (SPHHS) reviews key issues likely to be debated in the coming months as Congress and the National Institutes of Health (NIH) determine how the research will move forward.

New way to make stem cells avoids risk of cancer

A team of scientists has advanced stem cell research by finding a way to endow human skin cells with embryonic stem cell-like properties without inserting potentially problematic new genes into their DNA.

Discovery of 'master regulator' gene for skin development

Researchers at Oregon State University have found one gene in the human body that appears to be a master regulator for skin development, in research that could help address everything from skin diseases such as eczema or psoriasis to the wrinkling of skin as people age.

Stem cell therapy may lead to treatment for deafness

Deafness affects more than 250 million people worldwide. It typically involves the loss of sensory receptors, called hair cells, for their "tufts" of hair-like protrusions, and their associated neurons.

23 Mar 2009

Human adult testes cells can become embryonic-like

Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells.

23 Mar 2009

Protein called Shp2 is key to embryonic stem cell differentiation

Investigators at Burnham Institute for Medical Research (Burnham) have learned that a protein called Shp2 plays a critical role in the pathways that control decisions for differentiation or self-renewal in both human embryonic stem cells (hESCs) and mouse embryonic stem cells (mESCs).

Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates, and are capable of becoming only cells of a particular type of tissue.
