Immunofluorescent staining demonstrating fibroblasts expressing the Channelrhodopsin protein in heart scar tissue. The ChR2-expressing fibroblast (green) is in close proximity to cardiomyocytes (red) within scar.
Microscopic images showing heart tissue in mice (with cardiac muscle cells in red) after a heart attack. Untreated tissue (left) shows more DNA damage (green) than tissue that has been treated with an experimental drug (right).
Healthy airways (left) show well-defined layers of ciliated cells (green) and basal stem cells (red). In airways affected by cystic fibrosis (right), the layers are disrupted, and scientists identified a transitioning cell type that combines properties of both stem cells and ciliated cells (red and green in the same cell).
