mouse heart

A cross-section of an adult mouse heart. Cardiac fibroblasts (red) can be found surrounding the muscle cells (green), which are connected by intercalated discs (yellow). The spatial arrangement of the cells facilitates coordination and communication between these different cell types and plays important roles in cardiac development, responses to cardiac injury, and repair of cardiac tissue.
