  • In this microscopic histology image, macrophage immune cells (shown in red and green) flock to the injured region of a damaged mouse heart three days after researchers injected adult heart stem cells within the yellow dotted area. Researchers report Nov. 27 in Nature that stem cell therapy helps hearts recover from heart attack by triggering an innate immune response that alters cell activity around the injured area so that it heals with a more optimized scar and improved contractile properties.
