regeneratives

Regeneratives refer to a broad field focused on restoring form and function to damaged tissues or organs, through natural healing processes or engineered interventions. The field encompasses regenerative biology, regenerative medicine, and related design approaches that aim to replace or repair biological systems.

In biology, regeneration ranges from cellular turnover to whole-organ regrowth. Many non-human species can regenerate extensively, such as planarians and salamanders, whereas humans exhibit variable and limited regenerative capacity across tissues like skin, liver, and the nervous system.

Core strategies in regenerative medicine include stimulating endogenous repair, transplanting cells or tissues, and using scaffolds and biomaterials to guide new tissue formation. Techniques encompass stem cell therapy (including embryonic, adult, and induced pluripotent stem cells), tissue engineering, decellularized matrices, gene therapy, growth factors, and extracellular vesicles.

Applications span wound healing, bone and cartilage repair, liver regeneration, and recovery after myocardial infarction, with nerve repair and organ replacement areas of active investigation. Some therapies are already in clinical use, while others remain experimental.

Challenges include ensuring safety and long-term efficacy, achieving proper integration and function, preventing immune reactions and tumorigenicity, and translating research into scalable, affordable treatments. Regulatory and ethical considerations also shape development.

Ongoing research aims to decode natural regenerative programs, enhance endogenous repair mechanisms, improve biomaterial design, and integrate gene editing, immunomodulation, and biofabrication to achieve durable regeneration.
