Scientists from Trinity College Dublin have identified a novel target that could help to identify cancer stem cells while they are in their inactive state. The scientists could then jolt these cells into action so that they could be eliminated by radio or chemotherapeutic approaches.
Age-related macular degeneration (AMRD) could be treated by transplanting photoreceptors produced by the directed differentiation of stem cells, thanks to findings by Professor Gilbert Bernier of the University of Montreal.
A sticky, protein-rich gel, created by Johns Hopkins researchers, appears to help stem cells stay on or in rat hearts and restore their metabolism after transplantation, improving cardiac function after simulated heart attacks, according to results of a new study.
In the breast, cancer stem cells and normal stem cells can arise from different cell types but tap into distinct yet related stem cell programs, according to Whitehead Institute researchers. The differences between these stem cell programs may be significant enough to be exploited by future therapeutics.
A new study from the Forsyth Institute is helping to shed light on latent tuberculosis and the bacteria's ability to hide in stem cells. Some bone marrow stem cells reside in low oxygen (hypoxia) zones. These specialized zones are secured as immune cells and toxic chemicals cannot reach this zone. Hypoxia- activated cell signaling pathways may also protect the stem cells from dying or aging. A new study led by Forsyth Scientist Dr. Bikul Das has found that Mycobacterium tuberculosis (Mtb) hijack this protective hypoxic zone to hide intracellular to a special stem cell type.
A pair of topical medicines (miconazole and clobetasol) already alleviating skin conditions each may prove to have another, even more compelling use: instructing stem cells in the brain to reverse damage caused by multiple sclerosis (MS).
A team of Cornell scientists has shown that stem cells confined inside tiny capsules secrete substances that help heal simulated wounds in cell cultures, opening up new ways of delivering these substances to locations in the body where they can hasten healing.
