Formaldehyde damages proteins, not just DNA

The capacity of formaldehyde, a chemical frequently used in manufactured goods such as automotive parts and wood products, to damage DNA, interfere with cell replication and cause cancer inspired new federal...

Research into fly development provides insights into blood vessel formation

Researchers working with flies at IRB Barcelona describe that the concentration of some small intracellular organelles determines the branching capacity of tracheal cells. Tracheal cells are analogous to the cells that form...

New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But...

Fertility genes required for sperm stem cells

The underlying cause of male infertility is unknown for 30 percent of cases. In a pair of new studies, researchers at University of California San Diego School of Medicine determined that...

Regulatory RNA essential to DNA damage response

Knowing when to hold them, and when to fold them, is a critical skill in professional gambling. But it's also pertinent for cells assessing DNA damage. It's essential for the cells to...

UCLA researchers use stem cells to grow 3-D lung-in-a-dish

By coating tiny gel beads with lung-derived stem cells and then allowing them to self-assemble into the shapes of the air sacs found in human lungs, researchers at the Eli and...

New procedure allows long-term culturing of adult stem cells

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the Aug..

Penn-led study resolves long-disputed theory about stem cell populations

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease. In tissues that t..

Neural stem cell transplants promote Parkinson’s recovery in non-human primates

Human parthenogenetic stem cells, derived from unfertilized oocytes, can be used without destroying potentially viable human embryos to generate unlimited supply of neural stem cells for transplantati..

Gut microbes’ metabolite dampens proliferation of intestinal stem cells

Intestinal stem cells are among the most rapidly dividing cells in the body, busily creating new cells to replace the ones that are constantly being sloughed off. But unlike stem cells elsewhere in th..
