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).
Heart muscle cells in an uninfected mouse (left) and a mouse infected with SARS-CoV-2 (right) with mitochondria seen in pink. The disorganization of the cells and mitochondria in the image at right is associated with irregular heartbeat and death.
Electron microscopy images showing a healthy scar containing collagen type 5 with scar fibers smoothly arranged in parallel (left) and unhealthy scar containing no collagen type 5 with a disorganized architecture with disarray of scar fibers (right).
