Immunofluorescence staining elucidates cellular and extracellular compositions pivotal for cardiac repair. All cell nuclei are seen in blue, while the red stain delineates cardiomyocytes. The extracellular matrix, crucial for structural integrity and signaling, is highlighted in green. Cyan staining reveals neurons, underscoring the neuro-cardiac interactions during regeneration.
