Cardiovascular Research: Improve stem cells' ability treat heart failure ♦ Faster way to treat the heart after a heart attack ♦ Molecular cause of heart condition

Bioengineered patch, molecular 'booster' could improve stem cells' ability treat heart failure Despite the intense activity and high hopes that surround the use of stem cells to reverse heart disease, scientists still face multiple roadblocks before the treatment will be ready for clinical prime time. Researchers are now finding ways to maximize the healing potential of stem cells by helping them overcome the inhospitable conditions of a damaged heart – bringing the promise of stem cell therapy for heart disease one step closer to reality.
Researchers develop a faster way to treat the heart after a heart attack For healing the heart after a heart attack, stem cell therapies show promise but are slow to implement. Researchers develop a new treatment called microsphere therapy that can be kept on-hand and administered more readily than stem cells.
Molecular cause of heart condition identified Researchers have teased apart the molecular basis for differences in behavior between healthy cells and those from patients with a cardiac condition and identified a drug treatment that partially restores function to diseased cells.
Stem cell exosomes used to induce damaged mouse hearts to self-repair A little more than a decade ago, researchers discovered that all cells secrete tiny communications modules jammed with an entire work crew of messages for other cells. Today, a team of researchers is harnessing the communications vesicles secreted by stem cells and using them to induce the damaged heart to repair itself.
