Zebrafish

Outline

• Capable of regenerating heart, spinal cord, retina, fins, and other tissues

• Especially valuable for studying heart development and regeneration—can fully restore heart structure and function after injury

• Transparent embryos and external development allow real-time imaging of regeneration

• Widely used in genetic studies thanks to powerful tools like CRISPR

• Ideal for research in regenerative medicine, cardiovascular biology, and drug discovery
