Definition

Regenerative therapies are medical treatments that harness the body’s natural ability to repair, replace, or regenerate damaged cells, tissues, or organs. These therapies include stem cell therapy, tissue engineering, gene editing, and biomaterials to restore normal function.

Importance in Science

1. Addressing Unmet Medical Needs

  • Chronic diseases (e.g., diabetes, heart failure, neurodegeneration) often involve irreversible tissue damage.
  • Regenerative therapies offer potential cures rather than symptom management.

2. Expanding Biological Understanding

  • Studying regeneration reveals mechanisms of cell differentiation, tissue patterning, and immune modulation.
  • Advances in stem cell biology, such as induced pluripotent stem cells (iPSCs), have revolutionized disease modeling and drug discovery.

3. Innovation in Research Methods

  • Organoids: Lab-grown mini-organs used to study development and disease.
  • CRISPR/Cas9: Enables precise genetic modifications, crucial for correcting inherited disorders.

Impact on Society
